Question
![**Problem Statement:**
Consider the following series:
\[
\sum_{n=1}^{\infty} 4(0.8)^{n-1}
\]
**Tasks:**
(a) Find the sum of the series.
Given: \( S_n = 20 \)
(b) Use a graphing utility to find the indicated partial sum and complete the table. (Round your answers to four decimal places.)
| \( n \) | 5 | 10 | 20 | 50 | 100 |
|----------|------|------|------|------|------|
| \( S_n \) | | | | | |
**Diagram Explanation:**
There is no graph or explicit diagram in this image; however, there is a table in part (b) where the partial sums of the series for different values of \( n \) (5, 10, 20, 50, and 100) need to be calculated and rounded to four decimal places. The cell under \( S_n \) for \( n = 5 \) is marked incorrect with a red "X". This indicates an error that must be corrected. The other cells are empty and require input based on calculations using the series.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fc1f0aebc-fbdc-4356-9367-76628cca066f%2F9c1fd7ec-021d-49b9-aeea-da16f0c90bc4%2Faq5n73s_processed.png&w=3840&q=75)
