Skipping not the next question but the one after it

Hello, 

I am having difficulty with creating logic for a question. I ask a question with four options. Let say question number 1:

1. A

2. B

100. Both

500. None

If they choose none, skip 2 questions or if they choose both, then do not skip anything. But If they choose A, I want them to answer question number 2 and skip question number 3 and if they choose B, I want them to skip question number 2 and answer question number 3. 

With this example, the choice B is easy, simply skip question 2. However the choice A is really difficult because I do not know how to create a logic that says skip not the next question, but the one after it. Can you please help me? 

Thank you
