Lesson: Sum of an Infinite Geometric Sequence Mathematics

In this lesson, we will learn how to calculate the sum of an infinite geometric sequence.

Lesson Plan

Students will be able to

understand when a geometric series is convergent and, thus, has a finite sum (i.e., when ),
find the sum of a convergent infinite geometric sequence using the formula , given sufficient information about the sequence,
convert recurring decimals to fractions by finding the sum of a geometric sequence.
