I'm lost on the factorial included here in this problem. Any help is appreciated!
sequence is $z_y= y! +2, Y \ge 1.$
Find $\sum\limits_{i=3}^3 z_i$.

Do you really mean $\displaystyle \sum_{i=3}^{3} z_i$? – Antonio Vargas Nov 07 '13 at 23:04

Maybe $i=0$ instead? – Nov 07 '13 at 23:06

Its i=3 as the lower limit not 0. I'm confused on the factorial. Is the problem just 3!+2, so 5? – tony Nov 07 '13 at 23:08

@joey, you sure it's not $i=1$? – dfeuer Nov 07 '13 at 23:10
