    Let thw second integer be x

    then the first = 2x

    and the third integer is = 6+x

    their sum = 74

    x+2x+6+x = 74

    4x + 6 = 74

    4x = 74-6 = 68

    x = 68:4

    x = 17

    then the first integer is 2*17 = 34

    the third integer is 17+6 = 23

    the integers are 17, 23 and 34
