WebFeb 26, 2024 · we know , Tn = Sn - S (n-1) =4n^2+n -4 (n-1)^2 - (n-1) =4 (n^2-n^2+2n-1)+ (n-n+1) =8n - 4 + 1. = 8n -3. hence , Tn = 8n -3. T1 =8 (1)-3 =5. WebThe sum of arithmetic progression whose first term is a and the common difference is d can be calculated using one of the following formulas: S n = n/2 (2a+(n−1)d) and S n = n/2 (a 1 +a n).

2, 4n - 1 and 5n + 2 are in AP, find the value of n - Cuemath
WebIn an AP, if S n = n (4n + 1), find the AP. Advertisement Remove all ads Solution We know that, the n th term of an AP is a n = S n – S n – 1 a n = n (4n + 1) – (n – 1) {4 (n –1) + 1} ...... [∵ S n = n (4n + 1)] ⇒ a n = 4n 2 + n - (n – 1) (4 n – 3) = 4n 2 + n – 4n 2 + 3n + 4n – 3 = 8n – 3 Put n = 1, a 1 = 8 (1) -3 = 5 WebIf you put n=1 into the S (n) formula, you get that the sum of the first 1 terms = 2/11. Now if you look at his a (n) formula that he works out and put n=1 into it, it does not equal 2/11. It equals 9/110 So the sum of the first 1 terms is 2/11, but the first term is not 2/11. Is there something I don't understand? Thanks in advance. WebMar 31, 2024 · S n = n(4n + 1) Formula: a = first term. d = common difference. Calculation: S 1 = 1 (4 × 1 + 1) ⇒ S 1 = 4 + 1 = 5. S 2 = 2 (4 × 2 + 1) ⇒ S 2 = 2 × 9 = 18. Second … greenpeace energy eg impressum
