Aschool cafeteria sold 1,600 slices of pizza the first week, 800 the second week, 400 the third week if this patter continues, in what week will the cafeteria sell 50 slices? explain your anwser

6th week

Step-by-step explanation:the number of weeks is moving in a geometric proportion

Remember Tn = ar^n-1

Tn = 50, r = 800/1600= 1/2, a = 1600

So 50 = 1600 * 1/2^ n-1

50/1600 = 1/2^ n-1

1/32 = 1/2^ n-1

2^ -5 = 2^ -n+1

Equating powers

-5 = -n + 1

-n = -6

n = 6

answer: no, but if it does it's a obvious pattern.
