WebSolution: The sum of n terms S n = 441 Similarly, S n-1 = 356 a = 13 d= n For an AP, S n = (n/2) [2a+ (n-1)d] Putting n = n-1 in above equation, l is the last term. It is also denoted by a n. The result obtained is: S n -S n-1 = a n So, 441-356 = a n a n = 85 = 13+ (n-1)d Since d=n, n (n-1) = 72 ⇒n 2 – n – 72= 0 Solving by factorization method, WebGiven, 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 …

WebWe first graph S (n). We focus on n=x. To find a (x), we use S (x) and S (x-1) to make a right triangle, with the points as vertices, and legs of height a (x) and a base of 1. Now, we look at the derivative. We can visualize the derivative as the limit of the slope of the line segment with endpoints (n,S (n)) and (x,S (x)) as n approaches x.
