Question
In Exercises $35-62,$ use appropriate limit laws and theorems to determine the limit of the sequence or show that it diverges.$$a_{n}=\frac{n}{2^{n}}$$
Step 1
We can express the sequence $a_{n}=\frac{n}{2^{n}}$ as a function $f(x)=\frac{x}{2^{x}}$ where $x$ is a real number. We are interested in the limit as $x$ approaches infinity, which is written as $\lim _{x \rightarrow \infty} f(x)$. Show more…
