Web30 Jan 2024 · Solution: 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 … Web13 Aug 2024 · The nth term of a sequence is 4n + 1 where n is a positive integer. a) Find an expression for the sum of the (n-1)th and nth terms of this sequence. Give your answer in simplest form. What I did: 4n + 1 + (4n) = 8n + 1 b) The sum of two consecutive terms in the sequence is 70. Work out the larger of the two terms. 8n + 1 = 70 8n = 69
WebThe sum of n terms of an AP can be found using one of the following formulas: S n = n/2 (2a+(n−1)d) S n = n/2 (a 1 +a n) Here, a = a 1 = the first term, d = the common difference, n = number of terms, a n = n th term, S n … Web20 Aug 2024 · S n = 3 + 7 + 13 + ... + t n. where .
