If the `p^(t h)` term of an A.P. is `q` and the `q^(t h)` term is `p ,` prove that its `n^(t h)t e r mi s(p+q-n)dot`

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)

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

If the m^(t h) term of an A.P. is 1/n and the n^(t h) terms is 1/m , show that the sum of m n terms is 1/2(m n+1)dot

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

If m times the m^(t h) term of an A.P. is equal to n times its n^(t h) term, show that the (m+n)^(t h) term of the A.P. is zero.

If m times the m^(t h) term of an A.P. is equal to n times its n^(t h) term, show that the (m+n)^(t h) term of the A.P. is zero.

If the m^(t h) term of an A.P. is 1/n a n d\ t h e\ n^(t h)t e r m\ i s1/m ,\ show that the sumof m n terms is 1/2(m n+1) where m!=ndot

If the n^(t h) term of an A.P. is (2n+1), find the sum of first n terms of the A.P.

if m t h term of an A.P. is n\ a n d\ n t h term is m , then write its m+n t h term.

If (m+1)^(t h) term of an A.P. is twice the (n+1)^(t h) term, prove that (3m+1)^(t h) term is twice the (m+n+1)^(t h) term.
