    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).
