    3, 6, 9, 22.5, 67.5, 236.25, 945
    A6
    B9
    C22.5
    D67.5

    Answer : 6

    Explanation:
    We have number of series  : 3 , 6 , 9 , 22.5 , 67 . 5 , 236.25 , 945

    So,

    3 × 1.5  = 4.5

    4.5 × 2  =  9

    9 × 2.5 = 22.5

    22.5 × 3 = 67.5

    67.5 × 3.5 = 236.25

    236.25 × 4 = 945

    So, We get our series 3 , 4.5 , 9 , 22.5 , 67 . 5 , 236.25 , 945

    We can say from given series " 6 "  is odd one .
