Raoul wants to create a weekly schedule for going to the gym. He wants to go to the gym the same three days each week, and he wants there to be at least one day in between each of his visits. How many different ways can Raoul schedule his weekly gym visits?

One day between gives us ...

Sunday, Tuesday, Thursday, Saturday, Monday ....
but that does not result in the same three days each week.
I don't understand the question.
