# 24: The Geometric Series


• 24.1: Finite Geometric Series
We now study another sequence, the geometric sequence, which will be analogous to our study of the arithmetic sequence. A geometric sequence is a sequence for which we multiply a constant number to get from one term to the next.
• 24.2: Infinite Geometric Series
In some cases, it makes sense to add not only finitely many terms of a geometric sequence, but all infinitely many terms of the sequence! An informal and very intuitive infinite geometric series is exhibited in the next example.
