If r > 1, then the series diverges. If r = 1, the root test is inconclusive, and the series may converge or diverge. The root test is stronger than the ratio test: whenever the ratio test determines the convergence or divergence of an infinite series, the root test does too, but not conversely. [1]
In mathematics, the comparison test, sometimes called the direct comparison test to distinguish it from similar related tests (especially the limit comparison test), provides a way of deducing whether an infinite series or an improper integral converges or diverges by comparing the series or integral to one whose convergence properties are known.

Abel's uniform convergence test is a criterion for the uniform convergence of a series of functions or an improper integration of functions dependent on parameters. It is related to Abel's test for the convergence of an ordinary series of real numbers, and the proof relies on the same technique of summation by parts. The test is as follows.
On Jan. 9, the retailer announced a series of “real estate changes” for the new year, including the future of several stores among the more than 1,150 locations nationwide.
The Stanford Achievement Test Series, the most recent version of which is usually referred to simply as the "Stanford 10" or SAT-10, is a set of standardized achievement tests used by school districts in the United States and in American schools abroad for assessing children from kindergarten through high school.
