    Question

    What is the missing number '?' in the series.
    7, 8, 18, 57, ?, 1165​​

    A.

    228

    B.

    232

    C.

    174

    D.

    224

    Correct option is B

    Given: 7, 8, 18, 57, ?, 1165
    Logic: (Previous number ×\times Natural number) + Natural number = Next number
    ×\times​ 1 + 1 = 8
    ×\times​ 2 + 2 = 18
    18 ×\times​ 3 + 3 = 57
    57 ×\times​ 4 + 4 = 232
    232 ×\times​ 5 + 5 = 1165
    The missing number is 232.
    Thus, correct option is (b).
