Formula for sum of finite geometric series
WebOct 11, 2024 · Sum of finite geometric sequence formula: A finite geometric sequence is the sequence of numbers, which has finite numbers. In finite geometric sequence, the last term is defined. The sum of terms of a geometric sequence is given by: S n = a ( r n − 1) r − 1, when r > 1 and S n = a ( 1 − r n) 1 − r, when r < 1. WebMar 27, 2024 · We can do the same analysis for the general case of a geometric series, as long as the terms are getting smaller and smaller. This means that the common ratio must be a number between -1 and 1: r < 1. Therefore, we can find the sum of an infinite geometric series using the formula .
