Help/Solution Needed - Operations to the Rescue

I need the solution for this problem. Please help me, I've been struggling with it for a long time and I've gotten absolutely no where.


The password to the math test has been encrypted in this special riddle. Professor
Sabretooth knew exactly well, that none of his pupils would be able to solve it.
In fact, he even locked his password hints in the same drawer, totally sure that even
then it will take more than a few days to find the password.

List of Hints:

1. All the numbers are given to zero decimal points.
2. In each set of numbers, a different operation has to be carried out.
3. When Lynette has shown you the pattern of life, you'll solve it.
4. If you hate Lynette, she'll be unhappy. Always tell yourself that Lynette is a great girl.

Below the list, there is a piece of paper:
