The devil challenges you to a game. He will think of a natural number, and you have one guess at it each day. (once he has thought of a natural number, he will never change it.) If you guess the number he is thinking of , he will let you out. Is there a strategy to follow so that you are sure of eventually getting out? (Remember - you have eternity.)
