I'm not sure what you mean by "the 3 consecutive numbers of 72".
Do you mean 3 consecutive numbers that ADD UP TO 72 ?
If that's what you want, then you can use this equation:
The middle number . . . . . x
The smallest number . . . . (x-1)
The biggest number . . . . . (x+1)
The equation: (x-1) + (x) + (x+1) = 72 .
Boil that equation down, and you discover that x=24 .
So the 3 numbers are 23, 24, and 25 .
