In a gp if the m+n th term is p
WebLet the first term be a and the common ratio be r. Then, the m th term is a r m − 1 and the n th term is a r n − 1, so we get a r m − 1 = n, a r n − 1 = m. We seek the ( m + n) th term, which is a r m + n − 1. Dividing the two equations, we get r m − n = n m r m + n = n m ⋅ r 2 n r m + n − 1 = n r 2 n − 1 m.
