    Light bulbs every 9 months : 9,18,27,36,45

    air filters every 3 months : 3,6,9,12,15,18,21,24,27

    she would change them both together (for the first time) at 9 months ... and (for the second time) at 18 months ... and again at 27 months ... well, basically, every time she changes a light bulb, she is changing an air filter ... although she is changing air filters in between those times
