----------------------------
Sequence: 7,15,24,....
-------------------
I ran a linear regression program on the data and
got the following regression equation:
f(x) = 8.5x -(5/3)
--------------------------
So, f(8) = 8.5(8)-(5/3) = 66 1/3
---
Round down to 66 gulls on day 8

None because the supermarket will do something on the 6th day because they are messing on the cars and customers costing them business and money. A real answer to a real question.
