Hello,

I am having difficulty solving a summation because both the upper bound is a different variable than the lower bound. The summation is as follows:

2n

E (i) = ?

i=5

The "E" represents the sigma. I had considered the following:

5(0)n + 5(1)n + 5(2)n = 15n

but I honestly have no idea if that is correct. Please let me know if I am on the right track. Thank you!
