1.  Maggie is training for the Cross-Country Meet.  On the first day she runs 500m.  Each day after that, she runs 250m more than the day before.  At this rate, Maggie thinks that she can reach her goal of 5km (5000m) in a single day on the 21st day.  Her sister says she will reach this goal on the 19th day.  (Remember 1km=1000m)

Day # d	Distance ran m
1	500
2	500+250=750

Continue the table of values.
