    Question

    From the given options, select the number that can replace the question mark (?) in the following series.
    9, 26, 65, 124, ?

    A.

    216

    B.

    214

    C.

    217

    D.

    215

    Correct option is C

    Given: 9, 26, 65, 124, ?
    Logic: Cube of natural number starting from 2 and (+1 , -1) alternate.
    2³ + 1 = 9
    3³ – 1 = 26
    4³ + 1 = 65
    5³ – 1 = 124
    6³ + 1 = 216 + 1 = 217
    Thus, the correct option is (c) 217
