**Instructions for Completing the Series Analysis:**

Use a graphing utility to find the indicated partial sum \( S_n \) and complete the table. Then use a graphing utility to graph the first 10 terms of the sequence of partial sums. For each series, compare the rate at which the sequence of partial sums approaches the sum of the series. (Select the correct graphs. Round your answers to four decimal places.)

**Problem:**

(a) \( \sum_{n=1}^{\infty} \left( 4 \left( \frac{1}{8} \right)^{n-1} \right) = \frac{32}{7} \)

**Table for Partial Sums:**

| \( n \) | 5   | 10  | 20  | 50  | 100 |
|---------|-----|-----|-----|-----|-----|
| \( S_n \) |     |     |     |     |     |

**Instructions for Table Completion:**

- Use a graphing utility to calculate each \( S_n \) value for \( n = 5, 10, 20, 50, \) and \( 100 \).
- Report your results to four decimal places.

**Graph Description:**

- Graph the sequence of partial sums for the first 10 terms.
- Analyze how quickly the sequence approaches \( \frac{32}{7} \).

This exercise will help you understand the behavior of infinite series and how partial sums converge to the series limit.

### Mathematical Expression
(b) \[\sum_{n=1}^{\infty} \frac{1}{n^2} = \frac{\pi^2}{6}\]

This summation represents the Basel problem, a famous result in mathematical analysis that describes the sum of the reciprocals of the squares of the natural numbers.

### Table
The table has two rows and six columns. The columns indicate different values of \( n \), which are 5, 10, 20, 50, and 100.

- **Row Headers:**
  - \( n \): Represents the number of terms in the partial sum.
  - \( S_n \): Represents the partial sum of the series for \( n \) terms.

- **Columns:**
  - The columns under \( n \) show specific values: 5, 10, 20, 50, and 100. The corresponding \( S_n \) boxes are meant to be filled with the calculated partial sums for these values of \( n \).

This setup is educational and likely involves calculating each partial sum to understand how \( S_n \) approaches \(\frac{\pi^2}{6}\) as \( n \) increases.
