The pattern made up of figure a-i is missing the last brick. What figure out of the figures in range 1-9 is the last brick to restore the pattern, and why?
Created by myself
I have a suggestion as to how to answer it - however identifying which brick fits is tricky and I don't think I've solved that part.
The pattern I think is:
a and i contain the same patterns, b and h do, c and g, d and f and e is on its own.
They are allowed to overlap provided that the top piece is the final colour (black or white). So figure 'i' must contain (somehow) a square, a plus sign or horizontal/vertical lines, a circle, something to make up an arrow/an arrow, a half circle.
