hope this will help you
3.14 on the length. but if you add to a graph send another one to my comment and show me
explanation
0.04, just divide 4 by 100
This sequence has generating function

(if we include
for a moment)
Recall that for
, we have

Take the derivative to get


Take the derivative again:


Take the derivative one more time:


so we have
