In the upper right corner of the space below 4 and 5 are 20 and 24. The rule is: if the number above is X, the numbers in the upper right corner are 5x+3, 5x+2, 5x+ 1, 5x- 1 from left to right, that is, 5x3+3 =18, 5x9.

The figures in the lower left corner really can't find the law, and the above contents are for reference only.
