This pattern is on the side of an arcade game machine.

Inside the big circle is a square. Inside that square is another circle. Inside that circle is another square … and so the pattern goes on and on.

Measure the diameters of the three largest circles. Use these measurements to figure out the diameters of the next three circles. When you have an answer, measure the diameters and see if you are right.
