Jason and Belinda play a game. Here are the rules:  1. There are $$26$$ marbles.  2. They take turns taking out marbles. In each turn, each player must take out $$1$$ to $$3$$ marbles, and cannot choose not to take any marbles out.  3. The one who takes out the last marble loses the game.  If Jason takes some marbles out first, how many marbles should he take in the first turn so that he can make sure he will win the game?
