    Answer: The numbers are: 16, 11 and 48

    Step-by-step explanation:

    Let 1st number is a, second number is b and third number is c

    1st number is 5 more than the second so a=b+5

    The third number is 2 times the first so c=3*a=3 * (b+5)

    The sum of three numbers, so a+b+c=b+5+b+3 * (b+5) = 75

    b+5+b+3+3b+15=75

    5b+20=75

    5b=55

    b=11

    a=b+5=11+5=16

    c=3 * (b+5) = 3 * (11+5) = 3*16=48

    The numbers are: 16, 11 and 48
