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:
E (i) = ?
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!
