SUMMARY
The limit of the sequence \(\frac{(-1)^n}{n}\) as \(n\) approaches infinity is 0. This conclusion is derived from the fact that \((-1)^n\) alternates between 1 and -1, while \(\frac{1}{n}\) approaches 0. By applying the Squeeze Theorem, it is established that the oscillating behavior of the numerator does not affect the limit, as the denominator grows indefinitely. Therefore, the limit is definitively 0.
