43, 45, 47, 50, 52, 56, 58

how do you get from one number to the next

I can see it's

+2, +2, +3, +2, +4, +2

but what's the mathematical expression that can show that

the restrictions are that +2 has to be used every other time and their are only 2 expressions

So i need to find the one that goes in every other spot
