Let's try to identify a pattern or rule in the sequence:

1, 3, 7, 8, 21, 49, 76, 224, 467.

I'll first check the differences between consecutive terms.

**Differences between consecutive terms**:
- \( 3 - 1 = 2 \)
- \( 7 - 3 = 4 \)
- \( 8 - 7 = 1 \)
- \( 21 - 8 = 13 \)
- \( 49 - 21 = 28 \)
- \( 76 - 49 = 27 \)
- \( 224 - 76 = 148 \)
- \( 467 - 224 = 243 \)

The differences are: 2, 4, 1, 13, 28, 27, 148, 243.

We can try analyzing the second differences:

**Second differences**:
- \( 4 - 2 = 2 \)
- \( 1 - 4 = -3 \)
- \( 13 - 1 = 12 \)
- \( 28 - 13 = 15 \)
- \( 27 - 28 = -1 \)
- \( 148 - 27 = 121 \)
- \( 243 - 148 = 95 \)

The second differences do not follow a clear linear or quadratic pattern, but the irregular growth in the differences suggests this sequence may not follow a simple polynomial or arithmetic formula. 

However, it is possible that this sequence is generated by a more complex, non-linear recurrence relation or a rule that isn't easily deduced by simple methods.

Do you want me to explore deeper (e.g., look for recurrence relations, check for special number properties, or graph it)? Let me know!

---
Here are 5 questions that build on this:
1. Could the sequence involve multiplication or a mix of operations?
2. Could this sequence represent a recursive function?
3. What are the next terms after 467 in this sequence?
4. Can we fit this sequence to a custom function or formula?
5. Could this sequence be modeled as a combination of multiple simple sequences?

**Tip**: Analyzing first and second differences can help determine if a sequence follows a linear or quadratic pattern!

Consecutive unknown equation find it: 1, 3, 7, 8, 21, 49, 76, 224, 467.
