x = smallest number

x+1 = next consecutive number

x+2 = third number.....   they all add up to 72

x  +  x+1  +  x+2 = 72

3x+3=72

3x=69

x=23         and 24 and 25

Since the 3 numbers are consecutive, that means:

72/3 =24 is the mean or the average.

24 -1 =23 is the 2nd number.

24 + 1 =25 is the 3rd number.

So, 23, 24, 25 are the three numbers.
