If you're 8 feet away from a door and with each move you advance half the distance to the door. How many moves will it take to reach the door.
Common Wrong Answers
“4 moves”
This guess assumes that moving half the distance each time will eventually lead to reaching the door, but it overlooks the fact that the distances keep halving infinitely.
“8 moves”
This guess suggests that after 8 moves, you will have covered the 8 feet, but each move only covers half the remaining distance, never actually reaching the door.
“1 move”
This guess implies that one move is sufficient to reach the door, which is incorrect because each move only covers half the distance, so you will still be 4 feet away after the first move.
