In a practice test on this website I found a pattern that I cannot figure out.
Can someone help me?
The answer is
The arrow's position is cyclic with cycle $4$: up-down-left-right so the fifth square must contain an up arrow. Option B is eliminated.
There is a small square surrounding a circle every $2$ squares (cycle $2$) so there wouldn't be a square surrounding any circle for the fifth square. Option E is eliminated.
Finally, we see that there are two white circles in the first, two grey circles in the second, and this cycle of $2$ repeats. Hence there will be two white circles in the fifth square. Options C and D are eliminated.
