Hey folks,
I'm currently studying sequences and the like in Calc 2, and I went to Wikipedia for another explanation about them. The example given in the article http://en.wikipedia.org/wiki/Series_%28mathematics%29" seems to be incorrect to me.
The example is this:
[itex]\sum _{n=0}^{\infty }{2}^{-n} = 2[/itex]
I was thinking it's equal to zero though, since when n is really large, then the bottom gets really big so the whole fraction would head to zero.
Am I wrong or is the author wrong?
