Answer 3

So if you look at the image above in the earlier post. n is your index. It starts at 0, but could start at any value. The final term is going to be N, which is an arbitrary number. Then you are taking a raised to n, incrementing one by one and summing the terms. Hence the name summation notation.

Hope this helps.
