**Problem Statement**
1. Find \(\lim_{n \to \infty} \sup(s_n)\) and \(\lim_{n \to \infty} \inf(s_n)\) for the sequence:
\[
s_n = 1 + \frac{1}{n}
\]
2. Find \(\lim_{n \to \infty} \sup(s_n)\) and \(\lim_{n \to \infty} \inf(s_n)\) for the sequence:
\[
s_n = n
\]
3. Find \(\lim_{n \to \infty} \sup(s_n)\) and \(\lim_{n \to \infty} \inf(s_n)\) for the sequence:
\[
\{s_n\} = \{1, 0, 1, 0, 1, 0, \ldots\}
\]
**Explanation**
- **1st Sequence:** \( s_n = 1 + \frac{1}{n} \)
- As \( n \) approaches infinity, \( \frac{1}{n} \) approaches 0. So, \( s_n \) approaches 1.
- **2nd Sequence:** \( s_n = n \)
- As \( n \) approaches infinity, the sequence itself diverges to infinity. Therefore, the supremum also approaches infinity.
- **3rd Sequence:** Alternating Sequence \( \{1, 0, 1, 0, 1, 0, \ldots\} \)
- The sequence alternates between 1 and 0 indefinitely.
**Conclusion**
- For each sequence, identify the limiting behavior using the supremum and infimum concepts as required.
