    Complete the series. 31,29,24,22,17,(….)
    Question

    Complete the series.
    31,29,24,22,17,(….)

    A.

    13

    B.

    12

    C.

    14

    D.

    15

    Correct option is D

    Given: 31, 29, 24, 22, 17, (...)

    31 to 29: Subtract 2

    31−2=29

    29 to 24: Subtract 5

    29−5=24

    24 to 22: Subtract 2

    24−2=22

    22 to 17: Subtract 5

    22−5=17

    It alternates between subtracting 2 and subtracting 5.

    Continue the pattern:

    From 17, subtract 2 (next in the pattern):

    17−2=15

    So, the missing number in the series is 15.

    The correct answer is (D) 15.
