    Question

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

    13, 17, 25, 37, 53, __________

    A.

    69

    B.

    63

    C.

    73

    D.

    65

    Correct option is C

    Given: 13, 17, 25, 37, 53, ?
    Logic:  The differences between consecutive terms is increasing by 4 each time.
    17 - 13 = 4
    25 - 17 = 8
    37 - 25 = 12
    53 - 37 = 16
    The differences are: 4, 8, 12, 16.
    This pattern is increasing by 4 each time.
    The next difference should be 16 + 4 = 20.
    53 + 20 = 73
    Thus, the next term in the series is 73.
    Thus, the correct answer is (c) 73.
