WebIn an AP, if Sₙ = n (4n + 1), find the AP Solution: Given, the expression for the sum of the terms is Sₙ = n (4n + 1) We have to find the AP. Put n = 1, S₁ = 1 (4 (1) + 1) = 4 + 1 = 5 Put n =2, S₂ = 2 (4 (2) + 1) = 2 (8 + 1) = 2 (9) = 18 The AP in terms of common difference is given by a, a+d, a+2d, a+3d,......., a+ (n-1)d So, S₁ = a WebSolution If in an A.P., S n = qn 2 and S m = qm 2, where S r denotes the sum of r terms of the A.P., then Sq equals q3.
