[" Is pla term of an "A*P*(1)/(9)" is and "q" th tom ts "(1)/(p)],[" then the sum of pq teumis? "]

If the p^(th) term of an A.P. is (1)/(q) and q^(th) term is (1)/( p) , show that the sum of pq terms is ((pq+1) )/(2) .

If the p th term of AP is (1)/(q) and its q th term is (1)/(p) show that sum of pq terms is (1)/(2)(pq+1)

If the p^(th) term of an A.P.is (1)/(q) and q^(th) term is (1)/(p) and sum of pq terms is 25pq, then find the value of pq.

If p^(th) term of an A.P is (1)/(q) and q^(th) term of A.P is (1)/(p) then sum of the first pq terms is

If the sum of p terms of an A.P. is q and the sum of q terms is p, then the sum of p+q terms will be

If the sum of p terms of an A.P. is q and the sum of q terms is p, then the sum of p+q terms will be

If p th term of an A.P. is 1/q and q th term is 1/p prove that the sum of the first pq terms is 1/2[pq+1]

If the pth term of an AP is 1/q and the qth term is 1/p , show that the sum of pq terms is ((pq+1))/2 .

If the sum of p terms of an AP is q and the sum of q terms is p, then show that the sum of p+q terms is -(p+ q) . Alos, find the sum of first p-q terms (where, p gt q )

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