# Evaluating Limits of Sequences Algebraically - Expii

In many cases, such as $$\lim_{n\to\infty} 2^{1/n}$$, we can interpret a sequence limit as a function limit towards infinity. Sometimes we just need to reason directly, like for $$\lim_{n\to\infty} (1+x+x^2+\dots+x^n) = 1+x+x^2+\dots$$ (infinite geometric series).
