Sequences and Series**

If the series converges, then must also converge and is said to converge absolutely. The Ratio Test for Absolute Convergence. Let be a series with positive terms and let . Case 1. If L < 1, the series is absolutely convergent. Case 2. If L >1, the series is divergent. Case 3. If L = 1, the test is inconclusive. Apply a different test. ................
