To get the answer, you need to specify how much each thing cost.
Answer:
47=4n-3

N=11 btw
The pattern is dividing by 4 so it would be: 640 (divided by 4), 160 (divided by 4), 40 (divided by 4), 10 (divided by four), 5/2.
The next number would be 10/4 or 5/2 when simplified. (I’d go with 5/2 because teachers liked simplified numbers)
