Answer 2

1/1! + 2/3! + 3/5! ... n/(2n-1)!
∞
<=> ∑ n/(2n-1)! =~1,36 (-> e/2 ? idk... ^^)
n=1

Anyways... you need a while loop which exits when the difference between the last and current result is smaller than a certain (small) value. That would end with an approximation of the sum of this sequence.
