# It needs some thinking but solvable and nice

Replace the question mark with your solution

That was easy!

The figures are n-cubes with half the size of the larger one. The numbers show in which half the little cube is in each coordinate:

2 1   -> high x, low  y -> top right
2 2   -> high x, high y -> bottom right
1 2 2 -> low  x, high y, high z -> back's bottom left


The next one is the tesseract, which can be divided in 16 half-sided cubes.

The one we want is at the top right, back and far side in the w-dimension:

See? If I measured my time answering this question, it would be like this:
