We know that if a power series converges, then it converges absolutely. So, we consider . We have the ratio of the n+1 term and the n-th term is
If , then converges. So,
converges. So, we know that the radius of the convergence is .
Now we consider ...
The Radius and Interval of Convergence of Power Series are found. The solution is detailed and well presented. The response received a rating of "5" from the student who posted the question.
