    Question

    Which number from among the given options will come in place of (*) in the given number series?
    1, 1, 2, 8, 3, 27, 4, (*), 5, 125...

    A.

    96

    B.

    64

    C.

    36

    D.

    32

    Correct option is B

    Given number series: 1, 1, 2, 8, 3, 27, 4, (*), 5, 125...
    The series alternates between two sequences:
    The first sequence consists of the numbers: 1, 2, 3, 4, 5 (which increases by 1).
    The second sequence consists of the numbers: 1, 8, 27, (*), 125.
    Now, let's identify the pattern in the second sequence, which corresponds to the cubes of natural numbers:
    1 = 1³
    8 = 2³
    27 = 3³
    (*) = 4³ = 64
    125 = 5³
    From this analysis, we see that the missing number (*) corresponds to 43 = 64.
    Conclusion: The number that will come in place of (*) is 64.
    So, the correct answer is: (b) 64.
