About This Quiz & Worksheet How is the ratio test for series convergence used? Gauge your knowledge of this test and working with general terms by going through the quiz and worksheet.

The ratio test and the root test are two important tests to check the convergence or divergence of series. In the ratio test first, we compute the ratio of positive terms lim n → ∞ | a n + 1 a n |.

The ratio and root tests are two methods for determining this radius of convergence R. Ratio Test: The ratio test is one means to determine whether a series is convergent or not.
