if the sum of `m` terms of an `A.P`.is to the sum of `n` terms as `m^2` to `n^2` show that the `mth` term is to the `nth` term as `2m-1` to`2n -1`

if the sum of m terms of an A.P is to the sum of n terms as m^(2) to n^(2) show that the mth term is to the n th term as 2m-1 to 2n-1

If the sum of m terms of an A.P, is equal to the sum of n terms of the A.P ., then the sum of (m + n) terms is

If the sum of m terms of an AP is the same as the sum of its n terms , show that the sum of its (m+n) terms is zero .

Find the sum of 'n' terms of an A.P. whose nth term is 2n+1.

Find the sum of n terms of an A.P. whose nth term is (2n+1).

If the ratio of sum of m terms of an AP to the sum of n terms of the same AP is (m^(2))/(n^(2)) .Then prove that the ratio of its mth and nth terms is 2m-1:2n-1.

If the sum of m terms of an A.P. is same as the sum of its n terms, then the sum of its (m+n) terms is

If the sum of m terms of an A.P. is same as the sum of its n terms, then the sum of its (m+n) terms is

If the sum of m terms of an A.P. is same as the sum of its n terms, then the sum of its (m+n) terms is
