Best ResponseYou've already chosen the best response.0I know the answer, but I was wondering if there was a method to solve it without guessing/inferring what the i1 of \[\left(\begin{matrix}n \\ i1\end{matrix}\right) a ^{n(i1)} b ^{i1}\] is.

Best ResponseYou've already chosen the best response.0if you substitute i1 with k, it's right. Mine formula is just so that i can equal the nth term. Your n(th term) would need to be decreased by 1. Just technicalities.
