### Ratio test

#### Know More

1 The ratio test states that if L < 1 then the series converges absolutely if L >1 then the series is divergent if L = 1 or the limit fails to exist then the test is inconclusive because there exist both convergent and divergent series that satisfy this case It is possible to make the ratio test applicable to certain cases where the limit L fails to exist if limit superior and limit
