Question

Select the number that can replace the (?) in the following series.
2, 7, 14, 23, ?, 47

A.

21

B.

38

C.

34

D.

28

Correct option is C

Given: 2, 7, 14, 23, ?, 47
Logic: Each number is increased by odd consecutive numbers starting from 5.
7 - 2 = 5
14 - 7 = 7
23 - 14 = 9
So, follow this pattern
34 - 23 = 11
47 - 34 = 13
Hence, missing number is 34.
Thus, the correct answer is (c).
