Amit Sharma answered |
The pattern is + 5, + 20, + 80, + 320, ...... i.e. + (5 × 12), + (5 × 22), + (5 × 42), + (5 × 82),.....
So, missing term = 427 + (5 × 162) = 427 + 1280 = 1707
So, missing term = 427 + (5 × 162) = 427 + 1280 = 1707

The middle letters are static, so concentrate on the first and third letters. The series involves an alphabetical order with a reversal of the letters. The first letters are in alphabetical order: F, G, H, I , J. The second and fourth segments are reversals of the first and third segments. The missing segment begins with a new letter.

Explanation:
To solve this question, we need to identify the pattern in the given letter series and find the missing letters.
Pattern:
Looking at the given series, we can observe the following pattern:
1. The first letter is 'b'.
2. The second letter is 'a'.
3. The third letter is 'c'.
4. The fourth letter is 'b'.
5. The fifth letter is 'b'.
6. The sixth letter is 'b'.
7. The seventh letter is 'a'.
Missing Letters:
Based on the pattern, let's find the missing letters one by one:
1. The first missing letter is the second letter in the series. According to the pattern, it should be 'a'.
2. The second missing letter is the fourth letter in the series. According to the pattern, it should be 'c'.
3. The third missing letter is the sixth letter in the series. According to the pattern, it should be 'c'.
4. The fourth missing letter is the eighth letter in the series. According to the pattern, it should be 'a'.
Therefore, the correct series with the missing letters filled in is "baacbcbcba".
Options:
Let's now check the given options to see which one matches the correct series:
Option A: "acbb" - This option does not match the correct series as it does not include all the missing letters.
Option B: "bacc" - This option matches the correct series as it includes all the missing letters in the correct order.
Option C: "bcaa" - This option does not match the correct series as it includes the missing letters in the wrong order.
Option D: "cabb" - This option does not match the correct series as it includes the missing letters in the wrong order.
Therefore, the correct answer is option B: "baccc".

Number Series Pattern:
The given number series is 0.15, 0.3, ____, 1.2, 2.4. We need to identify the pattern in the series in order to find the missing term.
Explanation:
To identify the pattern, let's look at the difference between consecutive terms in the series:
- The difference between the first and second terms is 0.3 - 0.15 = 0.15.
- The difference between the second and third terms is missing.
- The difference between the third and fourth terms is 1.2 - 0.3 = 0.9.
- The difference between the fourth and fifth terms is 2.4 - 1.2 = 1.2.
Pattern Analysis:
From the given differences, we can observe the following pattern:
- The difference between consecutive terms is increasing by a factor of 0.6.
- The first difference is 0.15 and the second difference is 0.9.
- The missing term should have a difference of 0.15 + 0.6 = 0.75 with the second term.
Calculating the missing term:
To find the missing term, we can add the calculated difference to the second term:
0.3 + 0.75 = 1.05
Therefore, the missing term in the number series is 1.05.
Verification:
Let's verify the pattern by checking the difference between consecutive terms:
- The difference between the first and second terms is 0.3 - 0.15 = 0.15.
- The difference between the second and third terms is 1.05 - 0.3 = 0.75.
- The difference between the third and fourth terms is 1.2 - 1.05 = 0.15.
- The difference between the fourth and fifth terms is 2.4 - 1.2 = 1.2.
The pattern holds true, and the missing term 1.05 fits correctly into the series.
Conclusion:
The correct answer is option C) 0.6.

- The difference between the fourth and fifth terms is 2.4 - 1.2 = 1.2.
The pattern holds true, and the missing term 1.05 fits correctly into the series.

The correct answer is option C) 0.6.

Anoushka Bajaj answered |
every consecutive term is the previous term multiplied by 3
i.e. 1st term is 1/9
2nd term = 1st term x 3 --》 (1/9)x3= 1/3
3rd term = 2nd term x 3 --》 (1/3)x3= 1
4th term = 3rd term x3 --》 1x3=3
5th term = 4th term x3 --》 3x3=9
Therefore, 4th term will be 3.
So, 4th term will be 3.

The pattern is – 1, × 10 + 1, –1, × 10 + 1, – 1, × 10 + 1, .....
So, missing term = 10 × 10 + 1 = 101
So, missing term = 10 × 10 + 1 = 101
