There’s a problem with this week’s puzzle. The grid lays out as follows:


1-2-3: The first digit is less than the second digit by the same amount as the second digit is less than the third.
4-5-6: (Reversed) A square.
7-8-9: The square of an odd number.

1-4-7: A factor of 2-5-8.
2-5-8: Odd.
6-9: A cube.

One clue is incorrect. Which one is it? Fill in the digits in each box of the grid. (There are no 0′s.)
