I looked through some tutorials to find intervals of divergence and tests for divergence...(adsbygoogle = window.adsbygoogle || []).push({});

My series:

[PLAIN]http://img843.imageshack.us/img843/4193/51453212.jpg [Broken]

a and x are constants...

I did the ratio test and i get [tex]\rho[/tex]=1, so i tried to apply the limit test to see if a_{n}is zero or does not exist... The problem is, i am not sure about my method...

Do i divide the numerator(1) by n also, if so, the test gives a_{n}=0..... But then again i am not sure...

I learned about these tests from http://www.math.unh.edu/~jjp/radius/radius.html"...

Could someone please tell me if this sum is convergent or divergent (and the method you used to find this out)

Thanks
