I think you count the squares in the middle or radius ?
F(n)=f(n+1)=f(n+1)-5 because in the formula you are subtractinng
It tells us that:
(-2,4)
(-1,3)
(1,6)
(3,5)
(4,8)
Look at (3,5) ... it tells us that x = 3 and y = 5
So y = 5
-0.5 and 2 the difference is 2.5. 2.5 times 4 equals 10. 2 and -8 the difference is 10. 10 times 4 equals 40. -8 and 32 the difference is 40
