a. 120
b. 58
c. 182
d. 62
e. 86

A. 120

The series follows the pattern
56 + 21 = 58, 58 + 22 = 62, 62 + 23 = 70, 70 + 24 = 86, 86 + 25 = 118, 118 + 26 = 182
Therefore, 118 should be in place of 120.

2.The following numbers form a series. Find the odd one out.
733, 365, 181, 89, 38, 20
a. 365
b. 181
c. 89
d. 38
e. 20

D. 38

The series follows the pattern
(733 – 3) ÷ 2 = 365, (365 – 3) ÷ 2 = 181, (181 – 3) ÷ 2 = 89, (89 – 3) ÷ 2 = 43, (43 – 3) ÷ 2 = 20
Therefore, 43 should be in place of 38.

3.The following numbers form a series. Find the odd one out.
5, 21, 101, 501, 2510, 12501
a. 101
b. 21
c. 2510
d. 12501
e. 501

C. 2510

The series follows the pattern
5 × 5 – 4 = 21, 21 × 5 – 4 = 101, 101 × 5 – 4 = 501, 501 × 5 – 4 = 2501, 2501 × 5 – 4 = 12501
Therefore, 2501 should be in place of 2510.

4.The following numbers form a series. Find the odd one out.
1, 13, 37, 73, 125, 181
a. 13
b. 37
c. 73
d. 125
e. 181

D. 125

The series follows the pattern
1 + (11 × 1 + 1) = 13, 13 + (11 × 2 + 2) = 37, 37 + (11 × 3 + 3) = 73, 73 + (11 × 4 + 4) = 121, 121 + (11× 5 + 5) = 181
Therefore, 121 should be in place of 125.

5.The following numbers form a series. Find the odd one out.

The series follows the pattern
1 + 22– 1 = 4, 4 + 32– 1 = 12, 12 + 42– 1 = 27, 27 + 52– 1 = 51, 51 + 62– 1 = 86
Therefore, 51 should be in place of 47.
