Partial sum of arithmetic series
Web20 Aug 2016 · There are 7 terms in this series. We use the formula s_n = n/2(2a + (n - 1)d) to determine the sum of an arithmetic series. Here, d = -8, n = ?, a = 50 and s_n = 182. We will therefore be solving for n. 182 = n/2(2(50) + (n - 1)-8) 182 = n/2(100 - 8n + 8) 182 = n/2(108 - 8n) 182 = (108n)/2 - (8n^2)/2 182 = 54n - 4n^2 4n^2 - 54n + 182 = 0 By the quadratic … Web26 Mar 2016 · You can find the partial sum of a geometric sequence, which has the general explicit expression of. by using the following formula: For example, to find. follow these …
