the product of three consecutive integers is 22 less than the cube of the middle integer. Find the integer.

let the 3 consecutive integers be
x1, x, and x+1
( I wanted to cube x , not x+1 )
x(x1)(x+1) = x^3  22
x^3  x = x^3  22
x = 22
the 3 integers are 21 , 22, and 23
check: product of 3 numbers = 21x22x23 = 10626
cube of 22 = 10648
is the product 22 less than the cube? YES
