Find the mystery number. It is a 4 digit odd number. All the digits are different. None of the digits are 0 or 9. The tens digit is twice the ones digit, and the hundreds digit is twice the tens digit. The thousands digit is one less than the hundreds digit.

The ones digit is 1, 3, 5, or 7.
The tens digit must be either 2 or 6.
The hundreds digit must be 4.
The thousands digit must be 3
