    Question

    What will come in place of the question mark (?) in the given series?
    614, ?, 349, 249, 168, 104​​

    A.

    513

    B.

    469

    C.

    470

    D.

    452

    Correct option is C

    Given:
    614, ?, 349, 249, 168, 104
    Logic: adding consecutive perfect squares starting from 8.
    104 + 64 (8²) = 168
    168 + 81 (9²) = 249
    249 + 100 (10²) = 349
    Similarly;
    349 + 121 (11²) = 470
    470 + 144 (12²) = 614

    Thus, correct option is (c).
