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`

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 m^(th) term of an H.P. is n and the n^(th) term is m, show that its (mn)^(th) term is 1.

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

If mth term of an AP is 1/n and its nth term is 1/m , then show that its (mn)th term is 1

If mth term of an AP is 1/n and its nth term is 1/m , then show that its (mn)th term is 1

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^(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 mth term of an A.P. be 1//n and nth term be 1//m then show that its ( m n )th term is 1.

The mth term of an A.P. is (1)/(n) and nth term is (1)/(m). Its (mn)th term is :

The mth term of a H.P is n and the nth term is m . Proves that its rth term is m n//rdot
