    1st ⇒ 23

    2nd ⇒ 33

    3rd ⇒ 92

    Explanation

    Let the 1st term = x

    The 1st term is 10 less the 2nd term. So, the 2nd term = x + 10.

    The third term is 4 times the 1st term. So, 3rd term = 4*x = 4x

    The sum of these 3 numbers is 148.

    x + (x+10) + 4x = 148

    6x + 10 = 148

    6x = 138

    x = 23

    1st ⇒ 23

    2nd ⇒ 23+10 = 33

    3rd ⇒ 4*23 = 92
