Question

Why is this so for #3?

**Question 3:**

If we know that 

\[
\sum_{k=1}^{\infty} a_k = 10,000,
\]

then what can we say about 

\[
\lim_{k \to \infty} a_k?
\]

---

**Explanation:**

This question is asking about a series and the behavior of its terms as \( k \) approaches infinity. Given that the infinite series of terms \( a_k \) sums to 10,000, we need to assess what happens to the individual terms \( a_k \) as \( k \) goes to infinity. This relates to the concepts of convergence and divergence in series analysis. If an infinite series converges, it is necessary for the limit of the terms \( a_k \) to be zero as \( k \to \infty \).

### Section 10.4.3

We can be sure that \(\lim_{k \to \infty} a_k = 0\). 

This statement implies that as \(k\) approaches infinity, the sequence \(a_k\) converges to zero. This concept is often used in the analysis of series to determine convergence properties, such as whether a series is convergent or divergent.
