"WebMar 23, 2024 · 8. What happens is that the equality. ∑ k = 0 n a r n = a − a r n + 1 1 − r. only holds when r ≠ 1. When r = 1, it doesn't make sense. So, in order to study the behaviour of the series ∑ k = 0 n a r n when r = 1, we have to take another apprach. And that approach is: ∑ k = 0 n a 1 n = ∑ k = 0 n a = ( n + 1) a. Share.

WebIf we sum an arithmetic sequence, it takes a long time to work it out term-by-term. We therefore derive the general formula for evaluating a finite arithmetic series. We start with the general formula for an arithmetic sequence of $n$ terms and sum it from the first term ($a$) to the last term in the sequence ($l$): WebThe sum of finite geometric sequence formula is, S n = a (r n - 1) / (r - 1) S 1 ₈ = 2 (3 18 - 1) / (3 - 1) = 3 18 - 1.
