    Question

    Select the number that can replace the question mark (?) in the following series.
    848, 969, ?, 1282, 1478

    A.

    999

    B.

    1113

    C.

    1000

    D.

    1013

    Correct option is B

    Given: 848, 969, ?, 1282, 1478
    Logic: Difference of two consecutive terms is square of natural numbers starting from 112,122,132,142
    Check the differences between consecutive terms:
    969 - 848 = 121, ? - 969, 1282 - ?, 1478 -1282 = 196
    Observing the differences:
    121 → ? → ? → 196
    121 = 112
    196 = 142
    If the pattern follows 112,122,132,142
    122 =144
    132 =169
    The next term will be: 
    ? = 969 + 144 = 1113
    Thus, the correct answer is (B) 1113.
