WebMar 26, 2016 · If your pre-calculus teacher asks you to find the value of an infinite sum in a geometric sequence, the process is actually quite simple — as long as you keep your fractions and decimals straight. If r lies outside the range –1 < r < 1, an grows without bound infinitely, so there's no limit on how large the absolute value of an ( an ) can get.

WebThe general formula for the sum of the series is ∑ n = N ∞ r n = r N 1 − r which can be derived from the one you wrote and the fact that ∑ n = 0 N r n = 1 − r N + 1 1 − r which can be proved by induction. Notice that this last formula holds regardless of r (in particular, it holds also for r > 1 ). Share Cite Follow
