Question

Select the number from among the given options that can replace the question mark (?) in the following series.
29, 33, 41, 53, ?, 89, 113

A.

71

B.

79

C.

63

D.

69

Correct option is D

Given: 29, 33, 41, 53, ?, 89, 113
Logic: Numbers are increasing multiple of 4.
29 + 4 = 33
33 + 8 = 41
41 + 12 = 53
53 + 16 = 69
69 + 20 = 89
89 + 24 = 113
So, the missing term is 69.
Thus, correct option is (d).
