Evaluate [tex]\Sigma 2(1/10)^n[/tex] or explain why it diverges. (Infinity is on the top of the sum and n=1 on the bottom, I just didn't know how to put it in latex) This was a test question that I got wrong. I thought that it was a geometric series with r= 1/10. This would mean that r is less than 1 so the series would converge. Why is the question saying that it will diverge?
