WebGeometric series converge and have a sum to infinity if r <1. The common ratio must be between -1 and 1. A geometric series diverges and does not have a sum to infinity if r ≥1. If the terms get larger as the series progresses, the series diverges. The sum to infinity does not exist if r ≥1. The sum of the first n terms of a geometric series, up to and including the r term, is given by the closed-form formula: where r is the common ratio. One can derive that closed-form formula for the partial sum, sn, by subtracting out the many self-similar terms as follows: As n approaches infinity, the absolute value of r must be less than one for the … buttocks pain icd 10 code
