"consider a horizontal slab of air whose thickness(height) is dz. if this slab is at rest, the pressure holding it up from below must balance both the pressure from above and the weight of the slab. use this fact to find an expression for dP/dz, the variation of pressure with altitude, in terms of the density of air"
