+23246 Figure 1: 1 block and 4 triangular regions
Figure 2: 2 blocks and 4 triangular regions
Figure 3: 3 blocks and 4 triangular regions.
The triangular regions remain the same (they are always 4) but the number of blocks go up by one each time.
So, I would expect that the next figure would have 4 blocks and 4 triangular regions.
