WebJun 7, 2024 · The proof is as follows: Step 1: Let a be the first term and d be c.d. of the A P .Then Sm=n Step 2: n= m/2 {2a+ (m-1) d} 2n= 2am+ m ( m-1)d. ........ (1) And Step 3: S n= m m= n / 2 {2a+ (n-1) d} 2m = 2an+ n (n-1) d. ........... (2) Subtracting eq. (2)- (1), we get Step 4: 2a (m -1) + { m ( m - 1)- n ( n-1)}d = 2 n - 2 m
