Patterns across the table
112 Each answer is 3 more than the one before. 9 + 3 = 12.
235 Each answer is 7 more. 28 + 7 = 35.

4The answers go odd, even, odd, even 3 is odd, 6 is even, 9 is odd, 12 is even. They switch every time.
5Every answer is even 4, 8, 12, 16, 20, 24 are all even. Each answer is 4 more.

78 2 × 4 and 4 × 2 are the same, and row 4, column 2 is 8.
8Row 3, column 5 5 × 3 and 3 × 5 are the same, so swap the row and the column.

10False 1 to 4 is 3 more, but 4 to 9 is 5 more, and 9 to 16 is 7 more.
