I think its 1000 numbers because there from 1 to 999 there are 999 numbers, and then you add zero because it is also a whole number.
Find cost of shoes first (7.50)
subtract from the total value (55.20-7.50= 47.7)
then divide by 5.30 (47.7/ 5.3= 9)
Ninth term is 2.5
you are adding 0.5 each time
-1,-0.5,0,0.5,1,1.5,2,2.5

Mathematically speaking:
25 + 3n
