Sum of an infinite geometric series proof
WebProof: A series of the form a + ar + ar\(^{2}\) + ..... + ar\(^{n}\) + ..... ∞ is called an infinite geometric series. Let us consider an infinite Geometric Progression with first term a and common ratio r, where -1 < r < 1 i.e., r < 1. Therefore, the sum of n terms of this Geometric Progression in given by WebThe sum of infinite terms that follow a rule. When we have an infinite sequence of values: 12, 14, 18, 116, ... which follow a rule (in this case each term is half the previous one), and …
