a. 120

b. 58

c. 182

d. 62

e. 86

**Show Correct Answers**

**A. 120**

The series follows the pattern

56 + 2^{1} = 58, 58 + 2^{2} = 62, 62 + 2^{3} = 70, 70 + 2^{4} = 86, 86 + 2^{5} = 118, 118 + 2^{6} = 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

**Show Correct Answers**

**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

**Show Correct Answers**

**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

**Show Correct Answers**

**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.**

1, 4, 12, 27, 47, 86

e. 86

**Show Correct Answers**

**D. 47**

The series follows the pattern

1 + 2^{2}– 1 = 4, 4 + 3^{2}– 1 = 12, 12 + 4^{2}– 1 = 27, 27 + 5^{2}– 1 = 51, 51 + 6^{2}– 1 = 86

Therefore, 51 should be in place of 47.
