Bead RemovalDiscrete Mathematics Level 3
There are 100 beads on a necklace. 1 of them is red, the rest are blue. Working in the clockwise direction, we start from the red bead and remove every other bead. Right when the red bead is removed, how many blue beads are there left on the necklace?
Note: The first bead removed is the blue bead that is right next to the red bead in the clockwise direction.
