Jackson, Isabella, and Sebastian want to hide their bike lock combinations from their younger brothers and sisters, so they wrote them in codes. Each person's combination is on a different sheet of paper.

Each combination adds up to the same number.

  • All the numbers in Isabella's combination are perfect squares.
  • Only 1 number in Jackson's lock combination is odd.
