Good day all,(adsbygoogle = window.adsbygoogle || []).push({});

I received this picture through the facebook network last night. I took it as valid at first sight, but for some reason it bothered me; in other words, my skepticism kicked in. The author mentions and assumes the limit as "n goes to infinity" which is annotated in the summation, but there is no limit expressed. I've received a butt chewing previously for not including limits in my expressions, so I am a bit critical about it because I want my math to be outstanding. By the way, I'm sure the author meant to say 'the limit as n approaches infinity.'

I have attached both a picture of the check sent via facebook and a pdf of what I think he actually meant and what the expression on the check looks like to me. FYI - my program script is still really weak, which is why attached the information.

First and foremost, please do not give me the answer to his expression. Second, Am I on the right track? If not, I would appreciate some direction, but not the answer. Please note, I do have an answer and reasoning behind it. But of course my reasoning may be wrong if my assumptions are wrong.

I received some strange explanations of an answer on facebook, but of course it's facebook. In fact, one individual seems to think it's an equation. But I digress.

Your help is very much appreciated. Thanks in advance!
