A subset T of the integers is defined recursively as follows: . Base casе: 2 € T • Recursive rule: if k E T, then k+5 € T This problem asks you to prove that T is exactly the set of integers that can be expressed as 5m+2, where m is a non-negative integer. In other words, you will prove that x E T if and only if x= 5m+2, for some non-negative integer m. The two directions of the "if and only if’ are proven separately. 1. Use structural induction to prove that if k E T, then k = 5m+2, for some non-negative integer т. 2. Use structural induction to prove that if k 5m+2, for some non-negative integer m, then kET.

Transcribed Image Text:A subset \( T \) of the integers is defined recursively as follows:
- **Base case**: \( 2 \in T \)
- **Recursive rule**: if \( k \in T \), then \( k + 5 \in T \)
This problem asks you to prove that \( T \) is exactly the set of integers that can be expressed as \( 5m + 2 \), where \( m \) is a non-negative integer. In other words, you will prove that \( x \in T \) if and only if \( x = 5m + 2 \), for some non-negative integer \( m \). The two directions of the "if and only if" are proven separately.
1. Use structural induction to prove that if \( k \in T \), then \( k = 5m + 2 \), for some non-negative integer \( m \).
2. Use structural induction to prove that if \( k = 5m + 2 \), for some non-negative integer \( m \), then \( k \in T \).
