what is the next number in the pattern 5,3,7,5,9,7,11?

5  2 = 3
3 + 4 = 7
7  2 = 5
5 + 4 = 9
9  2 = 7
7 + 4 = 11
What pattern do you see?
What is the next number? 
You are adding 2 to every other number
so 5,3,7,5,9,7,11,?
5 to 7, 7 to 9, 9 to 11
3 to 5,5 to 7,7 to ?
?=9
I hope that makes sense. 
you add two

you are addin 2

the next number is 13 if tat helps
