It's algebra.

(a-1)*a=15*a+80 where a is the larger number. Take it from there.

The question is "The product of two consecutive integers is 80 more than 15 times the larger number", correct?

You really don't need a formula.  Its a simple question for guessing and checking.  You know you're multiplying 2 consecutive numbers, and you know that they're going to just be a little higher than 15, since the product is 80 more than 15 times the largest.  From there, its simple.

I had one on my test today that I couldn't figure out.

What number added to five, is the same when multiplied by five?

It couldn't be negative, and the only thing that I could think off was a negative decimal or something along those lines.
