30 customers the first week and 55 customers the second week and 80 customers the third week, what would you project for week 4

80 + 25 = ?

though if you're going off of the mean (average) week 4 would get 55 customers
oddly enough the median (middle number) is 55 as well. There is no mode (most common number)
to calc. average, 30+55+80=165/3=55

The first answer is still correct based on trend so i would go with that
