Determine if the following series converges or diverges and justify your decision.
![\[ \sum_{n=1}^{\infty} \frac{(1000)^n}{n!}. \]](https://www.stumblingrobot.com/wp-content/ql-cache/quicklatex.com-7a0edb4af5a045116d1ecf51caa610d7_l3.png "Rendered by QuickLaTeX.com")
The series converges by the ratio test since
![\begin{align*} \lim_{n \to \infty} \frac{a_{n+1}}{a_n} &= \lim_{n \to \infty} \left( \frac{1000^{n+1}}{(n+1)!} \right) \left( \frac{n!}{1000^n} \right) \\[9pt] &= \lim_{n \to \infty} \frac{1000}{n+1} \\[9pt] &= 0 < 1. \end{align*}](https://www.stumblingrobot.com/wp-content/ql-cache/quicklatex.com-d34b45425b75935cefe19b410ece1cc7_l3.png "Rendered by QuickLaTeX.com")
Hence, the series converges.
