In an ap the sum of m terms is equal to n
WebShow that the sum of (m + n) th and (m - n) th terms of an A.P is equal to twice the m th term Solution: Let a and d be the first term and common difference of the A.P respectively. It is known that the k th term of an A.P. is given by a k = a + (k - 1) d Therefore, a m + n = a + (m + n - 1) d a m - n = a + (m - n - 1) d a m = a + (m - 1) d Hence, WebApr 7, 2024 · Using formula (1), the sum of (m + n) terms is equal to, S m + n = ( m + n) 2 ( 2 a + ( m + n − 1) d) From equation (4), substituting ( 2 a + ( m + n − 1) d) = 0 in the above equation, we get, S m + n = ( m + n) 2 ( 0) ⇒ S m + n = 0 Hence, we have proved that the sum of (m + n) terms of this A.P. is zero.
