SUMMARY
The discussion focuses on using the Ratio Test to determine the convergence or divergence of the series defined by the term 100n/2^n. The key formula applied is p = lim┬(n→∞)[a_(n+1)/a_n], where p < 1 indicates convergence, p > 1 indicates divergence, and p = 1 means the test is inconclusive. Participants worked through the limit expression lim┬(n→∞)[(100(n+1)/2^(n+1))(2^n/100n)] to simplify and evaluate the limit, ultimately leading to a conclusion about the series' behavior.
