Strong induction please.

The problem presented is about a sequence defined by a recurrence relation. Here are the details as seen on the educational page: 1. **Problem Statement:** - Let \( a_0, a_1, a_2, \ldots \) be the sequence defined by the following recurrence relation: - \( a_0 = 51 \) - \( a_1 = 348 \) - \( a_i = 5a_{i-1} - 6a_{i-2} + 20 \cdot 7^i \) for \( i \geq 2 \) 2. **Objective:** - Use strong induction to prove that \( a_n = 2^n + 3^n + 7^{n+2} \) for any \( n \geq 0 \). 3. **Instructions:** - Complete the basis step of the proof. - What is the inductive hypothesis? - What do you need to show in the inductive step of the proof? - Complete the inductive step of the proof. **Additional Details:** - There are four distinct sections, each requiring input: 1. A field for completing the basis step of the proof. 2. A field for stating the inductive hypothesis. 3. A field for describing what needs to be shown in the inductive step. 4. A field for completing the inductive step of the proof. This page is designed for learners to engage with and complete the proof through the process of mathematical induction, facilitating an understanding of both the method and the specific sequence problem.
