2. 3, 4, 9, 8, 27, 16, (), (), fill in the number according to the law of safety?

Odd digits: 2, 4, 8, 16, 32 multiply by 2
Even digits: 3, 9, 27, 81 multiply by 3 in turn
2、3、4、9、8、27、16、（81）、（32）

There are 2, 3, 4, 9, 8, 27, 16, (), ()?

The last two brackets should be (81), (32)
The rules are as follows
2. 3, 4, 9, 8, 27, 16, (), () can be written as
2. 3, the square of 2, the square of 3, the third power of 2, the third power of 3, the fourth power of 2, (the fourth power of 3), the fifth power of 2)

Fill in the number according to the rule: 3, 2, 11, 4, 19, 8, 27, 16 () ()

For odd and even terms, see respectively:
Then the rule of odd term is to add 8 every time, and the rule of even term is to multiply 2 every time
So fill in 35, 32

Who can see the law between these numbers? 1, 2, 3, 5, 8, 12, 18, 27_ How much should be added next?
For example: 1,2,3,5,8,12,18,27_ How much should be added next?

The next number is 40 analysis: we can see that the difference of each adjacent number is: 1,1,2,3,4,6,9, the law between the differences is: starting from the fourth number, the nth value = the sum of the (n-1) number and the (n-3) number, that is, 3 = 2 + 1,4 = 3 + 1,6 = 4 + 2,9 = 6 + 3, therefore, the next difference should be 9 + 4, that is, 13, that is, the next number

2. 3, 4, 9, 8, 27, 16, (), (), fill in the number according to the law of safety?
