    Question

    Find the missing number in the following series.
    1, 6, 30, (…) , 360, 720

    A.

    124

    B.

    120

    C.

    118

    D.

    103

    Correct option is B


    Given: 1, 6, 30, (…) , 360, 720
    The logic here involves multiplying the numbers by decreasing factors: 6, 5, 4, 3, 2.
    1 × 6 = 6
    6 × 5 = 30
    30 × 4 = 120 (missing number)
    120 × 3 = 360
    360 × 2 = 720
    Thus, the missing number is 120.
    Hence, the correct answer is (b) 120.
