No, gravitational pull decreases as the square of the distance. So it decreases as altitude increases.

No, not at all ... it does the opposite, it decreases.
And it does so by a rate of about x= 1/y^2, the further you get away from any big mass. This is the Maths part. Now in words without any Mathematics:
It is something you won't feel in "human-possible" altitude. To "feel" such efffects, even astronauts would have to fly very far away. (Think of it, even the gravitational pull of the moon ist still that powerful (despite its distance) that it causes the tidal movement of the oceans on Earth .... However, if you fly away far enough, e.g. 50 times the distance of the moon, (that is just a quarter of the distance to Mars) then the Earth's gravity still has it's effects, but wouldn't play a big role any more.

Gravitational force declines with the inverse square of the distance from the center of the Earth. Since the atmosphere is thin compared to the radius of the Earth, the effect within the atmosphere is small. But by the time you are up 6000 kilometers, the force is 1/4 that on the Earth's surface.

The equation for the force (or pull) due to gravity is:
F = G (m1m2/r^2)
G is the gravitation constant. m1 and m2 are the two masses which act on eachother. And r is the square of the distance between the two of them.
As you can see, because r is in the denominator, the larger r is, the smaller the value of F that follows.
The other answers are correct, but we owe it to Newton at least to explain the force with his equation. Einstein's explanation is more complicated and you can look it up under General Relativity.

lets think it together while height increase the potential energy increase =mgh (m=mass,g=gravity,h=height)but there is another formula g=GmM(earth)/r^2 while it is going higher the potential energy increase by means of gravity.But while it is getting higher the distance increase so the dividor increases after a while this increase would be eternal ,endless.iF You divide a number with an eternal number the result would be zero if the gravity is zero than there wont be ANy potential energy there wont be any gravitational pull

It decrease with the altitude. It follows an inverse square property where as the radius from the center of one object increase the gravity decreases by double.

Depends how far up!

It doesn't it goes down.
