Captain Jonathan Frakes is leading his crew on a long, exhausting journey through the treasure vaults of the late Doug the Despot, who amassed fabulous wealth and hid it away in catacombs beneath the Capital City of Earth. Unfortunately for treasure hunters, Doug also laid several nasty booby traps along the way in the form of puzzles. One of these puzzles is five numbered doors. There is an inscription above them.

"One of us right; four of us wrong.
Four are alike; one doesn't belong."

The doors are numbered:
1, 2, 3, 4, 5

Which door should Captain Frakes choose?



Answer

Door #4 does not belong.

It is the only number not in the Fibonacci Sequence: 0, 1, 1, 2, 3, 5, 8..., where every number is the sum of the two previous numbers.
