    First number: 71/7

    Second number: 135/7

    Third number: 270/7

    Step-by-step explanation:

    First number = x

    Second number = 2x-1

    Third number = 2 (2x-1)

    x + (2x-1) + 2 (2x-1) = 68

    3x-1+4x-2=68

    7x-3=68

    7x=71

    x=71/7

    You can check by plugging in the x into the equation.
