    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.
