Hello, I was just wondering if someone can help me understand how to go about evaluating sums??? I am very new and lost as to how to get started... I don't understand the idea behind it.... For example: 2n E i i=5 thanks in advance!

And So?
Thanks for the reply... I don't really understand what each step is suppose to accomplish but.... But, trying to draw from your example, is this correct? [2n(2n+1)+2n(2n+2)+2n(2n+3)+2n(2n+4)+2n(2n+5)]/2 ?????????? and the result is 25?? Thanks again!

Where did the -10 come from? Since this is finite sum evaluation couldn't I evaluate it to a specific number? Thanks

Can someone help me understand what N is worth here? do I just count n as 1? or what? 4n E(n^3)i i=0

In the expression , is unknown. This is the sum with terms. Until the value of is given, it cannot be evaluated to a number.
