### Question 4

Examine this series: 11, 15, 38, 126. If another series is written with the same rule, what number would come in the place C: 7, A, B, C ?

A

102

B

30

C

2140

D

80

Soln.
Ans: a

Number 102 will come in place of (C). The pattern is: 11 X 1 + 4 = 15, then 15 X 2 + 8 = 38, then 38 X 3 + 12 = 126. Similarly, A = 7 X 1 + 4 = 11, B = 11 X 2 + 8 = 30, C = 30 X 3 + 12 = 102.

### Question 5

One number is wrong in the series. Find the wrong number.

A

5

B

3

C

Soln.
Ans: c

Series follows the pattern: −3 × 1 + 2 = 5, 5 × 2 + 2 = 12, 12 × 3 + 2 = 38, 38 × 4 + 2 = 154 and so on. Hence, the missing number will be 38. The number 39 is wrong here.
