- 1, 11, 21, 25, 31, 38 ➔ Arithmetic sequence (common difference is 10).
- 20, 14, 8, 2, -4, -10 ➔ Arithmetic sequence (common difference is -6).
- You start at an elevation of 12,000 feet and climb down 1,000 feet per day ➔ Arithmetic sequence (common difference is -1000).
- You add $2 to a piggy bank and add triple the money you added the previous day for one month ➔ Not an arithmetic sequence (this is a geometric sequence where the ratio varies).

**Responses:**
- 1, 11, 21, 25, 31, 38
- 20, 14, 8, 2, -4, -10

Thank you for your input. Given the responses for Question 13:
- Common Ratio: **1/3**
- a1: **12**
- a2: **4**

The responses can be matched to their respective terms:

1. **Common Ratio:** 1/3 - This indicates that each term in the sequence is produced by multiplying the previous term by 1/3.
2. **a1:** 12 - This is the first term of the sequence.
3. **a2:** 4 - This likely indicates the second term in a different sequence or derived from a context not directly indicated in the previous equations.

So based on your new information, the answers would be:

- **Common Ratio:** 1/3
- **a1:** 12
- **a2:** 4
