Question

Find the radius of convergence and the interval of convergence of the series.  Test the endpoints.

[summation symbol from n=1 to infinity] (x-3)n/3nn!

I am resubmitting this question.  I did not like the original answer.  Please show the steps of applying the ratio test to this series.  I came up with a radius of convergence of 3 and interval of convergence of [0,6].  I believe it does converge at both endpoints.  Thanks!
