Step-by-step explanation:

Based on the number of hours that are there it look like each hour that it goes 50 adds on

1. The time goes up one hour each time

2. The number of pages go up by 50

So if there are 4 hours then this would happen

 1              2                   3                    4

50+50=  100+50=      150+50=       200

50 adds on as the hour goes up.
