Question

Find the sum of the series: the problem looks like this, a 4 over the big E looking thing (which I can't show at this time) i = -1 below, 6i - 5 right next to it.

Answer 1

\[\sum_{}^{4}( 6i-5), i = \sqrt{-1}?\]

Answer 2

\[\sum_{i=1}^{4}\] 6i - 5

Answer 3

The 6i - 5 is right next to it not below it

Answer 4

(6*1-5) +(6*2-5) +(6*3-5) +(6*4-5) = 40
