To find the 22nd shape of the pattern,
Choose 22 divided by 4. The remainder is 2, making the 22nd shape a circle.
(Here's the breakdown: The repeating pattern is "square, circle, oval, circle," which consists of 4 shapes. Dividing 22 by 4 gives you 5 with a remainder of 2, meaning the 22nd shape corresponds to the 2nd shape in the pattern, which is a circle.)
