Beth and Bill are playing a game with 8 sided dice. A die has 2 blue sides, 2 red sides, 2 orange sides, and 2 green sides. They start with 200 dice and roll them. If an orange side comes up, they remove those dice and roll the remaining dice again. Write an equation to model Beth and Bill’s game.
y = 200(2/8)^x
3, 18, 108, 648, 3888,...
an=3(6)^n-1
