A snooker player is setting up the table before a game, and when he starts there are no balls on the table. As he takes the balls out of the six pockets, he notices something odd - the total points value of the balls in each pocket is one higher than the total points value in the previous pocket.
When he's put all the balls in position he notices that there is one missing. he then finds this ball on the floor.
What colour is this ball?
