A-level Maths : Geometric Series (investment problem) Example: A savings scheme is offering a rate of interest of 3.5% per annum for the lifetime of the plan. Alan wants to save up £20,000. WebA geometric series is a unit series (the series sum converges to one) if and only if r < 1 and a + r = 1 (equivalent to the more familiar form S = a / (1 - r) = 1 when r < 1). Therefore, an … Web6 Oct 2024 · This formula can also be used to help find the sum of an infinite geometric series, if the series converges. Typically this will be when the value of r is between -1 and 1. In other words, r < 1 or − 1 < r < 1. This is important because it causes the arn term in the above formula to approach 0 as n becomes infinite. flat machine screws
