Answer: , where w is the number of weeks (natural number) .
Step-by-step explanation:
Given: Ashley has 100 books that she wants to give away at the rate of n books per week.
Let 'w' be the number of weeks .
Then after first week w=1,
The number of books Ashley has after first week =
[Since she wants to give away at the rate of n books per week.]
Then after second week w=2,
The number of books Ashley has after second week =
Then after third week w=3,
The number of books Ashley has after third week =
Similarly for w weeks, the number of books Ashley has after w weeks =
Hence, the recursive function that gives the number of books Ashley has at any time is , where w is the number of weeks.

Check the picture below.
with negative angles, we go "clockwise", the same direction a clock hands move.
so -360-360-125 = -845.
so as you see in the picture, you go around twice, and then a little bit more, an extra 125°, landing you at -125°, or its positive counterpart, 235°.
