What are the best combination numbers?

[jim 824]

I'm not sure if I'm asking this question right. What are some of the best numbers that go together. Like 7 11 but I don't know if those would go together here. What I've read here I guess 11 22 would be one, right?  Any more?

odd numbers work well together           1,3,5,7,9  even numbers  2,4,6,8  ,number combinations , 1,4,7  2,5,8    3,6,9,    1,2,3
1,5,9  3,5,7    different combinations bring about different energies  which can be positive or negative     .not a simple question to answer .but indeed a good question .
