Reading Section 1.6-1.8 Problem Prove the following theorem: Theorem Vn E Z, n is either even or odd (but not both).

Prove the following theorem:
Theorem
Vn E Z, n is either even or odd (but not both).
Your proof must address the following points:
1. n is even or odd (and nothing else).
2. n is odd =
n is not even (hint: contradiction).
3. n is even
→ n is not odd (hint: contrapositive).
The first point is a bit more difficult. Start by making a statement about 0. Then assuming that
n is even, what can you say about n – 1 and n + 1? Likewise, assuming that n is odd, what can
- 1 and n + 1. Can you organize these facts into an argument that shows that
you say about n
you have accounted for all possible n E Z?](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F67cfbea1-c6da-422a-994b-91603e35be7f%2Fef731ef4-89ad-4078-a296-0554d81da14c%2Fvlr3ugj.png&w=3840&q=75)

Prove the following theorem:
Theorem
Vn E Z, n is either even or odd (but not both).
Your proof must address the following points:
1. n is even or odd (and nothing else).
2. n is odd =
n is not even (hint: contradiction).
3. n is even
→ n is not odd (hint: contrapositive).
The first point is a bit more difficult. Start by making a statement about 0. Then assuming that
n is even, what can you say about n – 1 and n + 1? Likewise, assuming that n is odd, what can
- 1 and n + 1. Can you organize these facts into an argument that shows that
you say about n
you have accounted for all possible n E Z?
