Question

Select the option that can replace the question mark (?) in the given series.
33, 38, 43, 54, 65, 70, 75, 86, ?

A.

97

B.

91

C.

108

D.

99

Correct option is A

Given: 33, 38, 43, 54, 65, 70, 75, 86, ?
Logic: The pattern alternates between +5, +5, +11, +11.
33 + 5 = 38
38 + 5 = 43
43 + 11 = 54
54 + 11 = 65
65 + 5 = 70
70 + 5 = 75
75 + 11 = 86
86 + 11 = 97
So, the missing term is 97.
Thus, correct option is (a).
