SUMMARY
The series \(\sum_{n=1}^{\infty} \frac{(-1)^n}{n}\) is an alternating series that converges to \(-\ln(2)\). This conclusion is derived from the properties of alternating series and the relationship between the series and the natural logarithm. The discussion highlights the manipulation of the series by factoring out constants and recognizing the form of the series related to known convergent series.
