"Web27 Mar 2024 · Therefore, we can find the sum of an infinite geometric series using the formula $\ S=\frac{a_{1}}{1-r}$. When an infinite sum has a finite value, we say the sum converges. Otherwise, the sum diverges. A sum converges only when the terms get closer to 0 after each step, but that alone is not a sufficient criterion for convergence. " - Summation r formula
