Find the next rule in rule 6. What's next to rule 4? I copied the answer. Tell me what the rules are.

The difference between the numbers in the upper left corner and the lower left corner is 2, and the numbers in the upper right corner and the lower right corner are also 2. The first relationship between the upper left corner and the upper right corner is the upper left corner multiplied by 2 plus 1, and the relationship between the lower left corner and the lower right corner is the lower left corner multiplied by 3 plus 1. The second relationship between the upper left corner and the upper right corner is that the upper left corner is multiplied by 3 plus 1 and the lower right corner is multiplied by 4 plus 2. Then the third relationship between the upper left corner and the upper right corner is that the upper left corner is multiplied by 4 plus 1, and the lower left corner and the lower right corner are multiplied by 4 minus 1. . . . .
