SUMMARY
The limit of the sequence defined by the expression \(\frac{1 - 2 + 3 - ... + (2n - 1) - 2n}{\sqrt{n^2 + 1}}\) as \(n\) approaches infinity is conclusively -1. Participants in the discussion emphasized that applying Stolz's theorem is unnecessary for this problem. Instead, simplifying the numerator into a more compact form is the recommended approach to reach the solution effectively.
