Many series do not fit the exact form of geometric series, oscillating series, p-series, or telescoping sums; one way to … Web9 de nov. de 2024 · The integral test for convergence is only valid for series that are 1) Positive : all of the terms in the series are positive, 2) Decreasing : every term is less than the one before it, a_(n-1)> a_n, and 3) Continuous : the series is defined everywhere in its domain. The integral test tell
Web1 / n diverges, with L = 1; 1 / n^2 converges, also with L = 1. Just with these two examples, we have shown that when L = 1, we cannot be sure of convergence or divergence. n^10 / n! is definitely not geometric, but the ratio test applies to all series. The geometric series test is just a specific case of the ratio test.
