1st term = 5
2nd term = 5 × 2 + 3 = 13
3rd term = 13 × 3 + 2 = 41
4th term = 41 × 2 + 3 = 85
5th term = 85 × 3 + 2 =257...
2nd term = 5 × 2 + 3 = 13
3rd term = 13 × 3 + 2 = 41
4th term = 41 × 2 + 3 = 85
5th term = 85 × 3 + 2 =257...
⇒ For every term at even position, the previous term is multiplied by 2 and 3 is added.
⇒ For every term at odd position, the previous term is multiplied by 3 and 2 is added.
⇒ For every term at odd position, the previous term is multiplied by 3 and 2 is added.
So the missing term is: 257 × 2 + 3 = 517

Shalini Patel answered |
1st term = 8
2nd term = 8 x 2 = 16
3rd term = 16 x 3 = 48
4th term = 48 x 2 = 96
5th term = 96 x 3 = 288
6th term = 288 x 2 = 576...
2nd term = 8 x 2 = 16
3rd term = 16 x 3 = 48
4th term = 48 x 2 = 96
5th term = 96 x 3 = 288
6th term = 288 x 2 = 576...
⇒ For every term at even position, the previous term is multiplied by 2.
⇒ For every term at odd position, the previous term is multiplied by 3.
⇒ For every term at odd position, the previous term is multiplied by 3.
So the missing term is: 576 × 3 = 1728

The series is 14, 28, 20, 40, 32, 64
Take three terms at a time. The notation be as follows:-
Let, First term = a = 14
It is evident that Second term= 2*a = 2 * 14 = 28 and,
The Third term = Second term - 8 OR ( 2*a - 8 ) = 28 - 8 = 20
Now consider the third, fourth and the fifth term.
Let, Third term = a = 20
It is evident that Fourth term= 2*a = 2 * 20 = 40 and,
The Fifth term = Second term - 8 OR ( 2*a - 8 ) = 40 - 8 = 32
Similarly consider fifth, sixth and the seventh(term to be found).
Let, Fifth term = a = 32
It is evident that Sixth term = 2*a = 2 * 32 = 64 and,
The Seventh term ( term to calculated) = Second term - 8 OR ( 2*a - 8 ) = 64 - 8 = 56

Third number = 4 + 2 = 6
Fourth number = 6 + 2 = 8
Fifth number = 8 + 2 = 10 and
Sixth number = 10 + 2 = 12
Hence, The answer is (b) 12.

Krishna Iyer answered |
When the letters are reversed in the group of Five, six, and seven letters.
5th to the left of 12th from the right end (27- 12 = 15th from left) means, 15 – 5 = 10th that lies in the 2ndgroup(6-11).
Therefore, 6 + 11 = 17 – 10 = 7th letter i.e. “G”.

Arnav Kumar answered |
Solution:
The given sequence is: A, B, D, H, ____, F
We have to find the missing term.
Explanation:
The given sequence can be interpreted as follows:
- Start with A.
- Move one step in the clockwise direction to get B.
- Move two steps in the clockwise direction to get D.
- Move four steps in the clockwise direction to get H.
- Move eight steps in the clockwise direction to get the missing term.
- Move sixteen steps in the clockwise direction to get F.
So, the missing term can be found by moving eight steps in the clockwise direction from H.
Moving eight steps in the clockwise direction from H, we get the letter 'P'.
Therefore, the missing term in the given sequence is 'P'.
Hence, option 'A' is the correct answer.

Vivek Patel answered |
1st term = 75
2nd term = 75 + 216 = 75 + 63 = 291
3rd term = 291 + 125 = 291 + 53 = 416
4th term = 416 + 64 = 416 + 43 = 480
5th term = 480 + 27 = 480 + 33 = 507...
2nd term = 75 + 216 = 75 + 63 = 291
3rd term = 291 + 125 = 291 + 53 = 416
4th term = 416 + 64 = 416 + 43 = 480
5th term = 480 + 27 = 480 + 33 = 507...
The differences are cubes of consecutive natural numbers in decreasing order from 6.
So, the missing term = 507 + 8 = 507 + 23 = 515
So, the missing term = 507 + 8 = 507 + 23 = 515

In this simple addition series, each number increases by 0.8.
Rule = (1st no.) (1st no. + 0.8 = 2nd no.) (2nd no. + 0.8 = 3rd number)...
Now (1.5) (1.5 + 0.8 = 2.3) (2.3 + 0.8 = 3.1) (3.1 + 0.8 = 3.9) (3.9 + 0.8 = 4.7)...
So the anwser is c = 4.7

The 1st to 5th terms are 0, 5, 22, 57, 116.
These terms are 1 – 1, 8 – 3, 27 – 5, 64 – 7, 125 – 9.
i.e. 13 – 1, 23 – 3, 33 – 5, 43 – 7, 53 – 9
These terms are 1 – 1, 8 – 3, 27 – 5, 64 – 7, 125 – 9.
i.e. 13 – 1, 23 – 3, 33 – 5, 43 – 7, 53 – 9
So, the nth term of the series: n3 – (2n – 1).
So, the 6th term of the series is 63 – (2 × 6 –1) = 216 – 11 = 205.

Understanding the Sequence
The given sequence is:
- 97, 83, 73, 67, 59, _____
To find the missing number, we need to identify the pattern in the sequence.
Identifying the Differences
Let's calculate the differences between consecutive numbers:
- 97 - 83 = 14
- 83 - 73 = 10
- 73 - 67 = 6
- 67 - 59 = 8
The differences are as follows:
- 14, 10, 6, 8
Finding the Pattern in Differences
The differences do not form a simple arithmetic sequence, but we can observe:
- The first difference (14) decreases by 4 to give the second difference (10).
- The second difference (10) decreases by 4 to give the third difference (6).
- The fourth difference (from 67 to 59) shows an increase, but importantly, it hints at a trend.
If we hypothesize that the next difference might continue this pattern, we could assume that the gap changes might stabilize around a certain difference.
Calculating the Next Number
Following the observed pattern, we can guess the next difference might be around 12 or stay close to previous differences. Thus:
- If we subtract a difference of 12 from 59, we get:
59 - 12 = 47
Conclusion
By analyzing the sequence and the pattern of differences, we conclude that the missing number is:
Option D: 47
This is consistent with the observed fluctuations within the sequence.

When letters are in reverse order in group of five
Letters each:
5th to the right of 12th from the right end(27-12 = 15th from left) means, 15 + 5 = 20
Which lies in 4thgroup(16-20). Therefore,
16 + 20 = 36 36 – 20 = 16th
Which is “P”.

To solve this question, we need to identify the pattern in the given sequence: AI, EO, IU, ___, UE. Let's analyze the given sequence:
1. Identify the pattern:
- The sequence starts with the vowels 'A' and 'I'.
- The next two vowels are 'E' and 'O'.
- The next two vowels are 'I' and 'U'.
- So, we can observe that the pattern is taking two vowels in an alternating manner.
2. Determine the missing term:
- Based on the pattern, the missing term should be two vowels taken in an alternating manner.
- The first vowel in the missing term should come after 'U', which is 'A'.
- The second vowel in the missing term should come after 'I', which is 'O'.
- Therefore, the missing term is 'AO'.
3. Check the options:
- Now, let's check the available options: OU, OI, OA, and UA.
- Among these options, only 'OA' matches the missing term 'AO'.
- Hence, the correct answer is option 'c) OA'.
Therefore, the missing term in the sequence AI, EO, IU, ___, UE is 'OA'.

Understanding the Series
The given series is: Z, S, W, O, T, K, Q, G, ?, ?
To decipher the pattern, we need to analyze the sequence of letters.
Identifying the Pattern
1. First Set of Letters:
- Z (26th letter)
- W (23rd letter)
- T (20th letter)
- Q (17th letter)
This part of the series follows a pattern of decreasing by 3:
- Z - 3 = W
- W - 3 = T
- T - 3 = Q
2. Second Set of Letters:
- S (19th letter)
- O (15th letter)
- K (11th letter)
- G (7th letter)
This segment decreases by 4:
- S - 4 = O
- O - 4 = K
- K - 4 = G
Continuing the Pattern
- For the next letter after Q:
- Q (17th letter) - 3 = N (14th letter)
- For the next letter after G:
- G (7th letter) - 4 = C (3rd letter)
Conclusion
The missing terms in the series are N and C.
Therefore, the correct answer is option A: N, C.

Understanding the Series
To solve for the missing term in the sequence "ajs, gpy, ?, sbk, yhqa", we need to analyze the pattern in the given terms.
Breakdown of the Terms
1. First Terms:
- a, g, ?, s, y
- Alphabet positions: a(1), g(7), s(19), y(25)
- Pattern:
- From a to g: +6
- From g to s: +12
- From s to y: +6
- Thus, the missing first letter must be: g + 6 = m (13).
2. Second Terms:
- j, p, ?, b, h
- Alphabet positions: j(10), p(16), b(2), h(8)
- Pattern:
- From j to p: +6
- From p to b: -14 (which wraps around the alphabet)
- From b to h: +6
- Thus, the missing second letter must be: p - 14 = c (3).
3. Third Terms:
- s, y, ?, k, a
- Alphabet positions: s(19), y(25), k(11), a(1)
- Pattern:
- From s to y: +6
- From y to k: -14
- From k to a: +6
- Thus, the missing third letter must be: y - 14 = m (13).
Conclusion
Combining the missing letters from each section, we arrive at the term "cm". Therefore, the complete sequence is:
- ajs
- gpy
- cm
- sbk
- yhqa
Thus, the correct answer is option 'B'.

The given sequence is a combination of two series :

Clearly, I consists of consecutive letters while II consists of alternate letters. So, the missing letter in I is F, while that in II is J. So, the missing terms i.e. 10th and 11th terms are J and F respectively.

To solve this question, we need to identify the pattern or rule followed by the given alphabet series and then find the missing term based on that pattern.
Given series: AYD, BVF, DRH, ?, KGL
Pattern: Let's analyze the given series step by step to identify the pattern:
1. The first letter in each term is in alphabetical order, i.e., A, B, C, D, etc.
2. The second letter in each term follows a pattern where it goes back two letters in the English alphabet, i.e., Y, W, U, S, etc.
3. The third letter in each term follows a pattern where it goes forward two letters in the English alphabet, i.e., D, F, H, J, etc.
Now, let's use this pattern to find the missing term.
Missing term:
1. The first letter should be the next letter in the alphabetical order after the last given term, which is 'H'. So, the first letter of the missing term should be 'I'.
2. The second letter should go back two letters from the last given term, which is 'R'. So, the second letter of the missing term should be 'P'.
3. The third letter should go forward two letters from the last given term, which is 'H'. So, the third letter of the missing term should be 'J'.
Therefore, the missing term in the given series is 'IPJ'.
Options:
a) FMI
b) GMJ
c) GLJ
d) HLK
Correct Answer: Option b) GMJ
Explanation:
The missing term 'IPJ' matches with option b) GMJ, which follows the same pattern as the given series. Thus, option b) is the correct answer.

3. The third letter in each term follows a pattern where it goes forward two letters in the English alphabet, i.e., D, F, H, J, etc.
Now, let's use this pattern to find the missing term.
Missing term:
1. The first letter should be the next letter in the alphabetical order after the last given term, which is 'H'. So, the first letter of the missing term should be 'I'.
2. The second letter should go back two letters from the last given term, which is 'R'. So, the second letter of the missing term should be 'P'.
3. The third letter should go forward two letters from the last given term, which is 'H'. So, the third letter of the missing term should be 'J'.
Therefore, the missing term in the given series is 'IPJ'.
Options:
a) FMI
b) GMJ
c) GLJ
d) HLK
Correct Answer: Option b) GMJ
Explanation:
The missing term 'IPJ' matches with option b) GMJ, which follows the same pattern as the given series. Thus, option b) is the correct answer.

- In each term the numbers are pairs of consecutive prime numbers.
- The letter between them has the place value equal to the product of the two numbers on either side of it.
∵ The next two prime numbers are 11 and 13 whose product is 143. The 143rd letter is (26 × 5 + 13) M.
as there are only 26 alphabet so there would be multiple rounds to reach 143 and we have to look at remainder.
∴ 11M13 is the next term.

The given sequence is a combination of two series :
I. Y,T, O and II. B, G, ?
I consists of 2nd, 7th and 12th letters from the end of the English alphabet, while
II consists of 2nd, 7th and 12th letters from the beginning of the English alphabet.
So, the missing letter in II is the 12th letter from the beginning of the English alphabet, which is L.
