WebJan 20, 2014 · We have, S n = 4n 2 + n put n = 1, we get S 1 = 4(1) 2 + 1 = 4 + 1 = 5 So, First term, a 1 = 5 Put n = 2 , we get S 2 = 4(2) 2 + 2 = 18 so, a 2 = S 2 - S 1 = 18 - 5 = 13 Put n = 3, we get S 3 = 4(3) 2 + 3 = 39 a 3 = S 3 - S 2 = 39 - 18 = 21 So, the required AP is 5, 13, 21, ..... 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, signs emotional abuse adults

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.

WebSolution Given that sn = 4n^2 + 2n. --------------- (1) Substitute n = 1 in (1), we get sn = 4 (1)^2 + 2 (1) = 4 + 2 = 6. So, Sum of the first term of AP is 6 i.e a = 6. Now, Substitute n = 2 in (1), we get sn = 4 (2)^2 + 2 (2) = 4 * 4 + 2 * 2 = 16 + 4 = 20. So, Sum of the first 2 terms = 20. Now, First-term + second term = 20 6 + a2 = 20
