Question
**Problem Statement:**

Use polynomial fitting to find the formula for the \(n\)th term of the sequence \((a_n)_{n \geq 0}\) which starts as follows: 

\[0, 0, 6, 18, 36, 60, \ldots\]

---

**Interactive Section:**  
### Derive the Formula
Use the input box below to find the formula for the sequence:

\[ a_n = \]

(Interactive input for the user to enter their solution.)

---

**Explanation:**
This sequence begins with the terms 0, 0, 6, 18, 36, 60, … and the task is to determine a polynomial formula, \(a_n\), that generates these terms for \(n \geq 0\).

---

**Tips for Solution:**
1. **Pattern Observation:** Check if the differences between terms suggest a particular degree of polynomial.
2. **Polynomial Equation Setup:** Use known polynomial fitting techniques to derive coefficients.
3. **Verification:** Substitute small values of \(n\) to ensure they produce corresponding terms of the sequence.

---

This exercise encourages understanding polynomial fitting methods, often used in mathematical analysis to model sequences or series data.
