8 x 1 - 2 = 6
6 x 2 - 3 = 9
9 x 3 - 4 = 23
23 x 4 - 5 = 87
87 x 5 - 6 = 429
6 x 2 - 3 = 9
9 x 3 - 4 = 23
23 x 4 - 5 = 87

Vikas Choudhury answered |
Explanation:
In this series, each number is repeated, and then 13 is subtracted to arrive at the next number.
The pattern can be described as follows:
● The first number is 53, and it is repeated.
● Then, 13 is subtracted from the first number to get the second number, which is 40.
● The second number is then repeated.
● Again, 13 is subtracted from the second number to get the third number, which is 27.
● The third number is repeated.
● Finally, 13 is subtracted from the third number to get the next number in the series, which is 14.
Therefore, the answer is 14, as it follows the established pattern in the series.
Therefore, the answer is 14, as it follows the established pattern in the series.

Lavanya Menon answered |
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

This is a simple division series, each number is one-half of the previous number.
In other terms to say, the number is divided by 2 successively to get the next result.
► 4/2 = 2
► 2/2 = 1
► 1/2 = 1/2
► (1/2) / 2 = 1/4
► (1/4) / 2 = 1/8 and so on.
► 2/2 = 1
► 1/2 = 1/2
► (1/2) / 2 = 1/4

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

Each number increases by 2.
Like -
First number is 2
Second number = 2 + 2 =4
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.

Nayanika Khanna answered |
**Solution**
To find the resultant of the second row, we need to follow the given rules and apply the operations to the numbers in the second row.
The second row is: 10 x 152
We will go through each number and apply the rules accordingly:
**Step 1:**
Starting with the first number, 10.
**Step 2:**
The next number is x. Since there is no information given about x, we cannot perform any operation with it at this point.
**Step 3:**
The next number is 152.
Since 10 is even and 152 is even, we need to subtract 10 from 152.
152 - 10 = 142
Therefore, the resultant of the second row is 142.

The solution is :

5 * 1.5 + 1.5 = 9
9 * 2.5 + 2.5 = 25
25 * 3.5 + 3.5 = 91 ≠ 95
91 * 4.5 + 4.5 = 414
Therefore wrong no. is 95
9 * .5 + .5 = 5
5 * 1.5 + 1.5 = 9
9 * 2.5 + 2.5 = 25
25 * 3.5 + 3.5 = 91 ≠ 95
91 * 4.5 + 4.5 = 414

The series can be represented as follows.
7 + 3 × 2, 20 + 2 × 3, 66 + 3 × 2, 138 + 2 x 3, 420 + 3 × 2,846
∴ The wrong term is 21.
∴ The new series will be
∴ The wrong term is 21.
∴ The new series will be
21 + 3 × 2, 48 + 2 × 3, 150 + 3 × 2, 306 + 2 × 3, 924
∴ 924 will be the fifth term in the new series.

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

The solution is :
3 * 2 = 6
6 * 2.5 = 15
15 * 3 = 45
45 * 3.5 = 157.5 ≠ 157
157.5 * 4 = 630
630 * 4.5 = 2835
Therefore, wrong no. is 157
3 * 2 = 6
6 * 2.5 = 15
15 * 3 = 45
45 * 3.5 = 157.5 ≠ 157
157.5 * 4 = 630
630 * 4.5 = 2835
Therefore, wrong no. is 157

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.

Explanation:
The given number series is: 2, 5, 10, 17, 26, 37, 50, 64
To identify the wrong term, we need to find the pattern or rule followed in the series.
Pattern:
If we observe the given series carefully, we can notice that each term is obtained by adding consecutive odd numbers starting from 1.
Let's break down the series and find the differences between consecutive terms:
2, 5, 10, 17, 26, 37, 50, 64
3, 5, 7, 9, 11, 13, 14
Analysis of Differences:
From the differences, we can see that the pattern is increasing by 2 each time.
Explanation:
- The difference between the first and second terms is 3.
- The first term is 2, and the second term is 5 (2 + 3).
- The difference between the second and third terms is 5.
- The second term is 5, and the third term is 10 (5 + 5).
- The difference between the third and fourth terms is 7.
- The third term is 10, and the fourth term is 17 (10 + 7).
- The difference between the fourth and fifth terms is 9.
- The fourth term is 17, and the fifth term is 26 (17 + 9).
- The difference between the fifth and sixth terms is 11.
- The fifth term is 26, and the sixth term is 37 (26 + 11).
- The difference between the sixth and seventh terms is 13.
- The sixth term is 37, and the seventh term is 50 (37 + 13).
- The difference between the seventh and eighth terms is 14.
- The seventh term is 50, and the eighth term is 64 (50 + 14).
Identifying the Wrong Term:
Now, we can clearly see that the difference between the seventh and eighth terms should be 13, but it is given as 14. Hence, the wrong term in the series is 64 (option D).
Conclusion:
The correct answer is option D. The wrong term in the given number series is 64.
The given number series is: 2, 5, 10, 17, 26, 37, 50, 64

- The difference between the fifth and sixth terms is 11.
- The fifth term is 26, and the sixth term is 37 (26 + 11).
- The difference between the sixth and seventh terms is 13.
- The sixth term is 37, and the seventh term is 50 (37 + 13).
- The difference between the seventh and eighth terms is 14.
- The seventh term is 50, and the eighth term is 64 (50 + 14).
Identifying the Wrong Term:
Now, we can clearly see that the difference between the seventh and eighth terms should be 13, but it is given as 14. Hence, the wrong term in the series is 64 (option D).
Conclusion:

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

Yes the option c is correct.
as you can see that the difference between two successive terms is in multiples of 4. following the series in the last term we had 16as difference so in the upcoming term 20 will be more than the previous one. hence 41+20=61.

Let the missing terms of the series be x1 and x2.
Thus, the sequence 2, 15, 4, 12, 6, 7, x1 x2 is a combination of two series :
I. 2, 4, 6, x1 and II. 15, 12, 7, x2
I consists of consecutive even numbers.
I consists of consecutive even numbers.
So, missing term, x1 = 8.
The pattern in II is - 3, - 5,......So, missing term, x2 = 7 - 7 = 0.

18 * 2 + 2 = 38
38 * 2 + 2 = 78 ≠ 80
78 * 2 + 2 = 158
158 * 2 + 2 = 318
Therefore, wrong no. is 80
3 * 2 + 2 = 8
8 * 2 + 2 = 18
18 * 2 + 2 = 38
38 * 2 + 2 = 78 ≠ 80
78 * 2 + 2 = 158
158 * 2 + 2 = 318
Therefore, wrong no. is 80
