Here are some sequence patterns. I have no clue.

This is two independent patterns overlaid. I show them both below, in arbitrary (top-to-bottom) order, with the fourth image included.
The patterns correspond to the (outer) square being a clock face with two hands. The first pattern has a hand with a hollow (white with a black border) square on its clockwise side. This moves 45° counterclockwise at each step:
The second has a hand with a solid black square on its counterclockwise side. This moves 90° clockwise at each step:
(Note that, in the third image, the solid black square overlays and obliterates the hollow square.)
Overlay the fourth images from the two series and you get Answer A:
This is just the (capital) letters “C”, “D” and “E” overlaid / overlapped with their mirror images:
So the fourth image is the (capital) letter “F” overlaid / overlapped with its mirror image:
which is Answer A.
If we number the images left-to right, top-to-bottom (so the top row is images 1, 2 and 3), then
So, again, the answer is A.
- Image 1 is image 3 plus image 7.
- Image 6 is image 2 plus image 4.
- This leaves images 5, 8 and 9 unaccounted for. Well, Image 5 is image 8 plus image A.
to all of the patterns is A
- the solid black square moves 90 degrees clockwise
- the not-filled square moves 90 degrees counter-clockwise and rotates 45 degrees
- of the two straight lines from the edge to the center, one moves 90 degrees clockwise and the other moves 45 degrees counter-clockwise
Each image is composed of the letter C, D, E and its mirrored version.
Number the images as follows:
1 2 3
4 5 6
7 8 9
Then, 3 and 7 together form 1; 4 and 2 together form 6; and A and 8 together form 5.
