    Question

    Select the number from among the given options that can replace the question mark (?) in the following series.
    1, 65, 114, ?, 175, 191​​

    A.

    160

    B.

    150

    C.

    154

    D.

    144

    Correct option is B

    Given Series:
    1, 65, 114, ?, 175, 191
    Logic: Add squares in decreasing order: (8², 7², 6², 5², 4²...)
    1 + 64 (8²) = 65
    65 + 49 (7²) = 114
    Similarly;
    114 + 36 (6²) = 150
    150 + 25 (5²) = 175
    175 + 16 (4²) = 191
    Thus, correct option is (b).
