    Select the wrong term in the following number series:9, 10, 19, 44, 93, 175
    Question

    Select the wrong term in the following number series:
    9, 10, 19, 44, 93, 175

    A.

    10

    B.

    175

    C.

    93

    D.

    44

    Correct option is B

    Given: 9, 10, 19, 44, 93, 175
    Logic: Difference is a perfect square of odd number from 1.
    10 - 9 = 1\sqrt {1}​​ = 1
    19 - 10 = 9\sqrt {9}​ = 3
    44 - 19 = 25\sqrt {25} = 5
    93 - 44 = 49\sqrt {49} = 7
    175 - 93 = 82\sqrt {82} \neq 81\sqrt {81}​ = 9
    So, the wrong term is 175.
    Thus, correct option is (b).
