### Solving Recurrence Relations

**Problem Statement**

Find the solution to the recurrence relation:

\[ a_n = -2a_{n-1} + 8a_{n-2} \]

with initial terms \( a_0 = 2 \) and \( a_1 = -2 \).

**Solution Approach**

To solve the given recurrence relation, we need a step-by-step approach to determine the general term \( a_n \), using the initial conditions provided.

- **Characteristic Equation**: Start by finding the characteristic equation of the recurrence relation.
- **Initial Conditions**: Use \( a_0 = 2 \) and \( a_1 = -2 \) to find the particular solution if needed.
- **General Solution**: Determine the general solution based on the characteristic equation.

You can input your answer in the provided space for \( a_n \). Analyze the pattern and relationships between consecutive terms to derive explicit formulas or utilize mathematical software for complex calculations.
