To solve the problem, we need to show that the m-th and n-th terms of a geometric progression (G.P.) are \(\sqrt{pq}\) and \(p\left(\frac{q}{p}\right)^{\frac{m}{2n}}\) respectively, given that the \((m+n)\)-th term is \(p\) and the \((m-n)\)-th term is \(q\). ### Step-by-Step Solution: 1. **Write the expressions for the given terms in G.P.:** The general term of a G.P. can be expressed as: \[ a_k = a \cdot r^{k-1} ...
