Limit - Comparison test :
Suppose that we have two series
If c is positive (that is c>0) and is finite then either both series converges or both series diverge.
P - series test:
The series is of the form
The original series is
We need to find the series similar to the original series but simpler.
The comparison series is
By using the p- series test,
Here p = 1
By the p - series test
By the Limit - Comparison Test,
