(200+300)/2 = 250
200 + 300 + 150 + 250 = 900
200
100, 150, 200, 250, 300, 350, 400, 450 . . .
-350 -300 -280 --250 -200
What comes in the middle of 200 and 300
200 + 300 + 250 = 750
250 (200+300=500%2=250)
(200+300)/2 = 250
300
200 + 300 + 150 + 250 = 900
300
200 + 300 200 + 200 + 100
250
200
It is then 300 rounded to the nearest hundred because 50 rounds up to 100
To the nearest hundred it is 200.
