WebAn infinite arithmetic series is the sum of an infinite (never ending) sequence of numbers with a common difference. An arithmetic series also has a series of common differences, for example 1 + 2 + 3. Where the infinite arithmetic series differs is that the series never ends: 1 + 2 + 3 …. The three dots (an ellipsis) means that the series ... Web6 Oct 2024 · Key Takeaways. A geometric sequence is a sequence where the ratio r between successive terms is constant. The general term of a geometric sequence can be written in terms of its first term a1, common ratio r, and index n as follows: an = a1rn − 1. A … pro auto care chickasha ok
