It means that the bus is consistently gaining speed. Specifically it gains 1 more meter per second than the previous second. So at 1 second it will move 1 m and at 2 seconds it will be at 3 m and at 3 seconds it will be at 6 m and so on.
At 5 seconds it will be at 15 m. I continue the pattern and end up with 15 m.
