If you don't understand, ask and I'll explain to you

Find the rule 8-2-32.12-3-48.32-8-

It's the square of the first number divided by the second number to get the third number
So the third group is 32-8-128
That's it

1. 3, 2, 6, 4, (), (), 12, 16

98

Find the rule 1,3,2,6,4, (), (), 12,16

1,3,2,6,4,(),(),12,16
Look at the odd and even terms separately
Odd number: 1,2,4, (), 16,; each number is the previous number × 2, so fill in the brackets with 8
Even terms: 3,6, (), 12; each number is the previous number + 3, so the brackets are 9

Fill in the numbers: 1, 3, 2, 6, 4______ ，______ ，12，16，… .

The first number required is item 6, even term, which is 3 times larger than 6;
The number is: 6 + 3 = 9;
Validation: 9 + 3 = 12;
The second number required is item 7, odd number, which is twice 4, that is:
4×2=8；
Validation: 8 × 2 = 16
So the answer is: 9, 8
