Answer:
4x/y4
Step-by-step explanation:
2(2x/y4)
2 x 2x/ y4
=4x/y4
If it was 3:55 the time after an hour and a half would be 5:25
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
