Think about this… What will happen when n becomes really big? It will get closer and closer to zero.
The Sum of an Infinite Geometric Series: ONLY IF: there is no sum IF:
1. Find the sum of the geometric series. a1 = 5 < 1 r = 25
2. Find the sum of the geometric series. a1 = 1 < 1 r =
3. Find the sum of the geometric series. a1 = 1/2 > 1 r = No Sum
4. Find the sum of the geometric series. a1 = 1 < 1 r =
5. Find the sum of the geometric series. a1 = 3 < 1 r =
5. Find the sum of the geometric series. a1 = 5 > 1 r = No Sum
6. Determine if the series is arithmetic, geometric, or infinite geometric. infinite geometric arithmetic geometric
