WebAn infinite geometric series is the sum of an infinite geometric sequence. When − 1 < r < 1 you can use the formula S = a 1 1 − r to find the sum of the infinite geometric series. An infinite geometric series converges (has a sum) when − 1 < r < 1, and diverges (doesn't have a sum) when r < − 1 or r > 1. In summation notation, an ... WebIn a geometric sequence, every term is obtained by multiplying its previous term by a constant (r, which is called the common ratio). If r > 1, then the terms are in ascending order. When r = 1, and the first term of a geometric sequence is 'a' then its sum is a · n. When r ≥ 1, the infinite geometric sequence diverges. ☛ Related Topics:
