Find the rules and fill in the numbers in brackets 12 5 10 10 8 15 （ ） （ ） 18 8 12 7 6 6 （ ） （ ）

12 5 10 10 8 15 (10) (10) --- every 4 numbers in a group, four four look, the corresponding number sum is 20
18 8 12 7 6 6 (1) (5) --- one group for every 2 numbers, 18 -- 12 -- 6 -- 1, the other group 8 --- 7 -- 6 -- 5

Shame can't be solved. Look for the numbers that are not arranged according to the rules Group 1: 24 8 10 22 32 44 Group 2: 10 12 15 18 24 30 37

The first group: 10 is not a regular number. The first group should be 24 8 14 22 32 442 to 4 plus 2, 4 to 8 plus 4. The next number should be 8 + 6 = 14, 14 to 22 plus 8. Each item is the number of the previous item plus 2 (n-1). (n is the number of items)

How much should I fill in the brackets below 32、45、（ ）、10、12、36
