    Question

    Which of the following numbers will replace the question mark (?) in the given series?
    4 , 9.6 , 23.04 , ? , 132.7104 , 318.50496

    A.

    B.

    55.296

    C.

    58.269

    D.

    51.865

    Correct option is B

    Given: 4 , 9.6 , 23.04 , ? , 132.7104 , 318.50496
    Logic: Every number multiplied by 2.4
    Explanation: 
    4 × 2.4 = 9.6
    9.6 × 2.4 = 23.04
    23.04 × 2.4 = 55.296
    55.296 × 2.4 = 132.7104
    132.7104 × 2.4 = 318.50496
    So, ? is replaced by 55.296
    Thus, Option B is the correct answer.
