"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. " - Proof of geometric series formula
