I took an online IQ test(https://www.test-guide.com/iq/free-iq-tests/free-iq-test.html) and encountered a question that I wasn't able to solve:
I did not find a pattern that produces the third image. I thought that it was a pattern of how the circles moved, but after trying very hard to look for a pattern, I could not find one. Any help in this problem is appreciated. Thank you.
