The atmosphere doubles in density roughly every 20 km
Actually the pressure increases by a factor of e=2.81828 every 10 km or so -- Earths' scale height.  Density increases commensurately for same temperature, but varies as PV=nRT otherwise.  So much steeper than you suggest -- density goes up more like a factor of 8 for every 20 km.

That's sad to see.
