`p^(th)` term of an A.P. is q and `q^(th)` term is p, then show that its `r^(th) ` term is `p+q-r`

If the p^(th) term of an A.P is q and q^(th) term is p, prove that its n^(th) term is (p+q-n)

If the p^(th) term of an A.P.is q and the q^(th) term is p, prove that its n^(th)term is(p+q-n)

The m^(th) term of an A.P. is n and n^(th) term is m its p^(th) term is

If p^(th) term of an AP is q, and its q^(th) term is p, then what is the common difference?

The p^(th) term of an A.P.is a and q^(th) term is b . Prove that the sum of its (p+q) terms is (p+q)/(2){a+b+(a-b)/(p-q)}

Suppose (m+n)th term of a G.P. is p and (m-n)th term is q, then its nth is

If p^(th) term of an A.P.is q and the q^(th) term is p .Find the first term of the A.P.
