Question

What should come in place of the question mark (?) in the given series?
18, 28, 40, 54, 70, ?

A.

88

B.

90

C.

87

D.

89

Correct option is A

Given:  18, 28, 40, 54, 70, ?
Logic: Series increases by consecutive even numbers starting from 10.
18 + 10 = 28
28 + 12 = 40
40 + 14 = 54
54 + 16 = 70
70 + 18 = 88
So, the missing number is 88.
Thus, the correct option is (a) 88.
