Test the series for convergence or divergence.\\ Use the Ratio Test and evaluate: \\ $\lim_{n \to \infty}$ \\ Since the limit is greater than 1, the series diverges\\ $\sum_{n=1}^{\infty} \frac{10^n}{(n+7)^2 \cdot 8^{n+2}} = \frac{10}{8}$ (Note: Use INF for an infinite limit.)

Step 1
Step 1: The Ratio Test states that if $$\lim_{n \to \infty} \left| \frac{a_{n+1}}{a_n} \right| = L$$, then the series converges if $L < 1$, diverges if $L > 1$, and the test is inconclusive if $L = 1$. Show more…

Use the Ratio Test to determine the convergence or divergence of the series. To do this, you need to use the limit as n approaches infinity of the absolute value of (a(n+1)/a(n)). If the limit is less than 1, the series converges. If the limit is greater than 1 or infinity, the series diverges.

Use the Limit Comparison Test to determine the convergence or divergence of the series ∑_{n=0}^{∑} 1/∑(n^2+1) lim_{n→∑} (1/∑(n^2+1)) / │ │ = L > 0 converges diverges
