In an A .P ., p -th term be q and q -th term be p , then show that (p + q ) -th term = 0 .

If the pth term of a H.P. be q and the qth term be equal to p, show that, its (p + q)th term is (pq)/(p+q) .

in a G.P (p+q)th term = m and (p-q) th term = n , then find its p th term

If P-th term of an arithmetic progression be Q and Q-th term be P.then show that (P+Q)thterm is O.

In an A.P. if p^(th) term is 1/q and q^(th) term is 1/p , prove that the sum of first pq terms is 1/2(pq+1) , where p ne q .

If the pth term of an arithmetic progression is q and the qth term is p, show that its (p+q)th term is 0.

if the Pth term of an A.P. is q and qth term is P.Then show that the nth term is p+q-n

If the pth term of an A.P. is q and the qth term is p , then find its rth term.

In an A.P. if m^("th") term is n and the n^("th") term is m, where m ne n , find the pth term .

If pth, qth and rth terms of on AP are a. b and c, then show that a(q - r) + b(r - p) + c(p - q) = 0.

If p^(th), q^(th), r^(th) and s^(th) terms of an A.P. are in G.P, then show that (p – q), (q – r), (r – s) are also in G.P.
