Question
For what values of the common ratio r is it possible to find the sum of an infinite geometric series? (Enter your answer using interval notation.)−1x1
Solution
The sum of an infinite geometric series can be found when the common ratio r is between -1 and 1, not inclusive. In interval notation, this is expressed as (-1, 1).
