It reduces by the inverse square ratio

Decreases, inversely proportional to the square of the distance between the centre of the earth and the centre of the object going upwards at any time. Note that the acceleration due to Earth's gravity is independent of the mass of the object going upwards.
g = GM / (r^2)

The force of attraction between two masses M1 and M2 is given by the formula
F = G.M1.M2/r^2 where G is the gravitational constant, and r is the distance between the centres of the two masses. Acceleration is F/M2 (in our case it is denoted by g, acceleration due to gravity) and will thus reduce inversely as the distance from earth increases.

yes as you go up there is less air, less air equals less resistance, this is why a few sky divers are tring to accually jump from outerspace so that they can break the speed of sound on free fall which is 700 miles an hour much much faster than you can get to down here where most sky diving takes place
