The ratio and root test fall when the limit of the ratio of n + 1th and nth terms of the series becomes _____?

The ratio test and root test are inconclusive when the limit of the ratio (or root) of successive terms is exactly 1.
These tests fail to determine convergence or divergence in this case.
