Please help with this problem from discrete math. Thank you!!!
### Recursively Defined Sequence We are given a sequence \( a_n \) defined recursively as follows: - \( a_0 = 0 \) - \( a_1 = 3 \) - \( a_n = 3a_{n-1} - 2a_{n-2} \) for \( n \geq 2 \) ### Objective We aim to prove that for all \( n \geq 0 \), the formula \( a_n = 3 \cdot 2^n - 3 \) holds true. ### Method We will use the method of **strong mathematical induction** to prove this claim. Strong induction is a powerful proof technique that allows us to assume the statement holds for all values less than \( n \) to prove it for \( n \). ### Proof Using Strong Induction Assume the statement is true for all integers up to \( n = k \), and prove it for \( n = k + 1 \).
