WebIf in an A.P. the sum of m terms is equal to n and the sum of n terms is equal to m,then prove that the sum of (m-n) terms is -(m+n). WebJul 26, 2024 · Let the first term of the AP be a and the common difference be d. Given: S m = m 2 p and S n = n 2 p. To prove: S p = p 3. According to the problem (m - n)d = 2p(m - n) Now m is not equal to n So d = 2p. Substituting in 1 st equation we get. Hence proved.
