Question

What should come in place of the question mark (?) in the given series?
18, 27, 22, 32, 30, 42, 42, ?

A.

48

B.

54

C.

52

D.

57

Correct option is D

Given: 18, 27, 22, 32, 30, 42, 42, ?​​
There are two series given:
1st series: 18, 22, 30, 42
2nd series: 27, 32, 42, ?
Logic: Numbers are increasing + 5, + 10 and + 15
27 + 5 = 32
32 + 10 = 42
42 + 15 = 57
So, the missing term is 57.
Thus, correct option is (d).
