You start with one triangle and in the first sequence you place 3 triangles on each side of the first triangle as so http://imageshack.us/photo/my-images/709/tri2.png/ < n=1
You then add triangles to the sides of the next lot http://imageshack.us/photo/my-images/812/tri3.png/ <n=2

Remember triangles will start taking place of other triangles so you can’t just go 3^n
