Q)

In series 1, only one number is wrong. If the wrong number is corrected, the series gets established following a certain logic. Complete series 2 with same logic and answer the given question.

Series 1: 8 9 20 63 256 1285
Series 2: 5 a b c d e

What will come in place of (e) ?


  • Explanation

    Given number series 1 follows the logic

    ⇒ 8×1+1=9

    ⇒ 9×2+2=20

    ⇒ 20×3+3=63

    ⇒ 63×4+4=256

    ⇒ 256×5+5=1285

    Similarly, series 2

    (a)⇒ 5×1+1=6

    (b)⇒ 6×2+2=14

    (c)⇒ 14×3+3=45

    (d)⇒ 45×4+4=184

    (e)⇒ 184×5+5=925

    Hence, Option C is correct.
