It's greater on the outside until it rises to a point in the atmosphere where the air is very thing. At that point, the pressure inside the balloon is greater which causes it to pop.

Why does air rush out of a hole in a balloon?
The pressure inside is greater than outside, or else the balloon would not blown up.
What has to happen for a balloon to inflate?
The pressure inside the balloon has to exceed the pressure outside the balloon.
Why does the pressure outside the balloon decrease as it rises?
The pressure outside the balloon doesn't change when the balloon rises. By a balloon rising, I assume that air is being placed into the balloon. As the balloon fills with air, the pressure inside the balloon will increase. Since the balloon can stretch, the increasing pressure against its inner walls will cause it to rise, or more correctly put, expand. Eventually, the balloon will be stretched to its fullest capacity if more air is placed inside it. When it pops, the bang you hear is the high pressure of the atmosphere inside the balloon equalizing with the lower pressure of the atmosphere outside the balloon.
What happens to the pressure of the air outside of the balloon as it goes higher?
The pressure inside the balloon will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
Can a balloon blow itself up?
A balloon can't blow itself up - it can only respond to internal and external forces. For example, if the pressure inside the balloon is greater than the pressure outside the balloon, it will inflate; if the pressure is greater than the balloon is able to stretch, it blows up. Balloons that are filled on the ground, for example, and then released into the sky may eventually blow up as they reach altitudes with lower air pressure.

Why does balloon become full when you blow air in it?
Once the air pressure inside the balloon is greater than the air pressure outside the surface it starts to fill. the higher the pressure inside the more the air acts against the inner rubber surface and the balloon gets harder. an empty balloon has the same air pressure inside and outside. Once you push any air in therefore you are starting to raise the air pressure inside.air molocules from you fill it up

Why do most balloons burst as they ascend high altitude?
The internal pressure of the gasses inside a balloon remains constant while external air pressure decreases as the balloon ascends. As the balance between the two changes, the pressure inside becomes progressively greater than the pressure outside, so the balloon expands. If it expands beyond the ability of the balloon material to contain it, the balloon will burst.
Is frictional force involved when blowing up a balloon?
Yes, there should be some friction. However, the main reason it costs you some effort is because the pressure inside the balloon is greater than the pressure outside.
What happens to the pressure of the air outside of the balloon as it goes higher?
The pressure inside the balloon will be higher because the balloon will try to get smaller and thus the balloon will ascent due to the low density of the helium inside the balloon.
Why does a balloon expend as you blow into it?
Air pressure - greater on inside than out.

How you know gas is inside the balloon?
If there were nothing inside the balloon - a vacuum - the balloon would quickly collapse due to the pressure of the atmosphere outside it. A firmer structure might resist the air pressure, but not a balloon.
What would change the size of a balloon?
Increased pressure on the inside, or decreased pressure on the outside.
Why does a balloon pop as it goes up to the sky?
the pressure has increased
