Consider the infinite series defined by:

A) What is the value of r from the ratio test?

B) What does this r value tell you about the series?

I'm online schooled. I don't have anyone to explain this to me properly. I looked up Youtube videos to get a better understanding of the concept and I'm still struggling to see the concept of doing the ratio test. If someone could help, that would be greatly appreciated. I also have to warn you, I ask a lot of questions, so just be prepared.

I think this has been asked and answered previously somewhere, but I couldn't find where, so:

#2**0 **

I still feel very confused.. I'm sorry. I got lost at the 1+n^{th }term. Why would you add the 2 on both sides of the fraction?

After that, I get the work. I tried solving for myself and I got the same answer. So that's the only question I have.

Thank you for helping, by the way!
