    Question

    Select the option that will fill in the blank and complete the given series.

    13, 16, 22, 31, 43, _________

    A.

    49

    B.

    58

    C.

    63

    D.

    53

    Correct option is B

    Given: 13, 16, 22, 31, 43, ?
    Logic: The differences are: 3, 6, 9, 12, which are increasing by 3 each time.​
    16 - 13 = 3, 22 - 16 = 6, 31 - 22 = 9, 43 - 31 = 12
    The next difference will be 12 + 3 = 15.
    Add the difference to the last term:
    43 + 15 = 58
    Thus, the next term in the series is 58.
    Thus, the correct option is (b) 58.
