x + (x+1) + (x+2) = 3x + 3 = 42
3x = 39
x = 13
Check to see if it fits the following equation.
x(x+1)(x+2) = 10728
3x = 39
x = 13
Check to see if it fits the following equation.
x(x+1)(x+2) = 10728

If the three terms are of a GP, then
a + ar + ar^2 = 42
a * ar * ar^2 = 10728
Hmmm. I suspect a typo, since the solutions are not rational. Maybe the three terms are from an AP. If so, then
a + a+d + a+2d = 42
a(a+d)(a+2d) = 10728
Again, no joy, since the solutions are not even real..
So what is the real question?
a + ar + ar^2 = 42
a * ar * ar^2 = 10728
