If pth term of a G.P. is P and its qth term is Q, prove that the nth term is `((P^(n-q))/(Q^(n-p)))^(1/(p-q))` .

If pth term of an A.P. is c and the qth term is d, what is the rth term ?

If (p+q)^(th) term of an A.P. is m and (p-q)th term is n, then the pth term is:

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 .

In a GP if the (m+n)th term is p and (m-n)th term is q then mth term is

In an A.P., the mth term is 1/n and the nth term is 1/m , find the (mn)th term.

In an A.P., of which a is the first term, if the sum of the first p terms is zero, show that the sum of the next q terms is (-a(p +q)q)/(p-1) .

In an A . P , if mth Term is n and nth term is m , where m nen , find the pth term .

If ‘a’ and ‘b’ are respectively the pth and qth terms of an A.P., show that the sum of (p + q) terms is (p+q)/2[(a + b) + (a- b)/(p - q)] .
