So we could say in general the loan amount, if we now generalize it to n instead of and n equals a number, we could say that it's equal to-- I'll actually take the p out of the equation, so it's equal to p, times 1 plus 1 over 1 plus i plus 1 over 1 plus i squared plus, and you just keep doing this n times, plus 1 over 1 plus i to the n.
