float x,addX;

void setup(){

size (400,400);

smooth();

}

void draw(){

background(255);

stroke(0);

strokeWeight(2);

addX = mouseX/3;

for ( x = addX;x < width;x *= 2){

line( x,height/20,x,height-(height/20));

}

println(x);

The problem is that when the program starts mouseX is initiialised to zero so addX is 0 so the loop counter x starts at 0 and will remain 0 since 2*x (2*0) is always zero so you have an infinite loop try changing the for loop to

for(x = addX + 1; x < width; x *= 2)

this will avoid the infinite loop

There could be some problems where you are putting addX = mouseX/3; in your draw statement.

I would do:

void mouseMoved() {
   addX = mouseX/3;
}

You might was to experiment and see what this does.
