Transcribed Image Text:## Problem Statement
**Prove the following statement:**
“For all integers \(a, b, c\), if \(a \mid b\) and \(b \mid c\), then \(a \mid (5b - 3c)\).”
### Instructions
- You need an introduction, body, and a conclusion.
- Do not be overly wordy. Excessive length reduces legibility.
- You may use information from the front page to assist you.

![**Mathematical Induction Proof Exercise**
**Problem Statement:**
Use the principle of mathematical induction to prove that:
\[ 4 + 8 + 12 + \ldots + 4n = 2n^2 + 2n \]
for all integers \( n \geq 1 \).
**Instructions:**
Write a complete proof consisting of an introduction, body, and conclusion. Clearly identify where the Inductive Hypothesis is applied. Strive for clarity and conciseness; excessive length reduces legibility.
---
**[Proof Outline]**
1. **Introduction:**
- State that the goal is to use mathematical induction to prove the given equation for all integers \( n \geq 1 \).
2. **Base Case:**
- Verify the equation holds for \( n = 1 \).
3. **Inductive Step:**
- Assume the statement is true for \( n = k \) (Inductive Hypothesis).
- Show the statement is true for \( n = k + 1 \).
4. **Conclusion:**
- Summarize why the base case and inductive step together complete the proof.
**Guidelines:**
- Ensure each part of the proof is logically connected.
- Clearly label the Inductive Hypothesis in the body of the proof.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F4640cd63-ee34-4c34-940b-cd98e9fa837c%2F74e3d1c2-0528-49d9-af83-49bb84f3da16%2Fy08usoq_processed.png&w=3840&q=75)
