    Post Question Of The Day (17-March-17)

    7,37,67,97

    number has be factor of 2 ,


    x-3d x-d x+d x+3d

    total common difference is 2d+2d+2d = 6d,, so common difference will be even.

    option 1 = 40 -- not possible as it will be more than 40+40+40 = 120 and we are talking about less than 100.

    option 4 is not possible- it is odd.

    as common difference is Even , number 2 cannot be taken oterwise cd cannot be even.

    so taking


    x+3d = 97 , x-3d=3---------x=50 but d is not a whole number
    x+3d= 97, x-3d=5---------------x=51 but d is not whole number

    x+3d=97, and x-3d=7--------x=52 and d=15------(it will work)


    so number will be x-3d = 52-45 = 7
    x-d=52-15=37
    x+d = 52+15 = 67
    x+3d=97
