Notice that Abel's test implies in particular that the radius of convergence is at least 1. It can also be applied to a power series with radius of convergence 2127: 2841: 129: 1626: 1461: 1646: 1382: 2540: 4037: 1330: 2535: 1180: 2447: 4025: 1213: 1078: 2473: 2393: 2122: 1540: 1276: 1136: 1107: 980:
This article is about the mathematical method of testing for the convergence of an infinite series. For the test for determining the flash point of petroleum, see

There are two slightly different versions of Abel's test – one is used with series of real numbers, and the other is used with 4147: 4032: 4015: 4010: 4020: 4005: 3119: 3307: 3092: 4000: 3617: 3371: 3058: 466: 2696:. 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 2124:

It is important to understand that this test is mainly pertinent and useful in the context of non absolutely convergent series
