From f/10, the stops are basically f/7.1, f/5, f/14, f/20. Two stops is double or half, one stop is multiplied/divided by a square root of 2.

Looks like I disagree with amehta which can be a silly thing to do, but my take is -
In addition to one at the correct exposure -
3 shot bracketed 1 stop is one at half as much light, and one at twice as much light
3 shot bracketed 2 stops is one at 1/4 the light and one at 4 times the light.
If you wanted to do the same thing manually, most cameras are set up at 1/3 stop clicks, so 3 clicks either way will be one F/stop.
What you said is correct. What I said was imprecise, so you are right to dispute it.
