Question

What would be an equation that gives you the 3 consecutive numbers of 72

Answer 1

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 .
