I don't think I could help you here without just giving you an answer, which we are not allowed to do. About the only thing I can suggest is that you go to a good website and learn about what the mathematical symbols mean. Google "mathematical symbols ellipsis" or just go to http://www.solving-math-problems.com/ellipsis.html and look for "repeating". The definition is clear and will help a lot here.

Then google for another article.  The definition in that article was quite clear, but if you are confused still, there are lots of articles on the internet about ellipsis.
