### Given an Arithmetic Series

The problem presents an arithmetic series with the following terms: 
- \( t(4) = 5 \)
- \( t(7) = 20 \)

The total number of terms in the series is 20. Answer each of the following questions based on this information.

**Questions to be Answered:**

1. **What is \( t(11) \)?**
2. **How can you represent the series in Sigma Form?**
3. **What is \( S(n) \)?**

Below the question prompts, there are four options (A, B, C, D) which display different series in Sigma notation:

**Option A:**
\[ \sum_{n=1}^{20} (4n - 15) \]

**Option B:**
\[ \sum_{n=1}^{20} (4n - 10) \]

**Option C:**
\[ \sum_{n=1}^{20} (5n - 15) \]

**Option D:**
\[ \sum_{n=1}^{20} (5n - 10) \]

Additionally, below these options, there are fields to be filled in by the user:
- **\( t(11) \) Field:** "type your answer..."
- **Sigma Form Dropdown:** "choose your answer..."
- **\( S(n) \) Field:** "type your answer..."

### Explanation Notes:
- **Sigma Notation:** This is a way to represent a sum of terms in a series.
- **Arithmetic Series:** A sequence of numbers in which the difference of any two successive members is a constant.
- **\( t(n) \):** Represents the nth term of the series.
- **\( S(n) \):** Represents the sum of the first n terms of the series.

To find the options correctly and determine the function for the arithmetic series, organize the information given and use standard formulas for arithmetic sequences and series.
