During a night flight, you observe a steady white light and a flashing red light ahead and at the same altitude. What is the general direction of movement of the other aircraft?

Explanation

The steady white position light is at the tail and is visible from behind; the flashing red light is the anticollision beacon, visible from all directions. Seeing a steady white light plus the beacon, and no red or green wingtip light, means you are behind the aircraft and it is flying away from you.
