Using the clues below, what four numbers am I thinking of?

The sum of all the numbers is 31.
One number is odd.
The highest number minus the lowest number is 7.
If you subtract the middle two numbers, it equals two.
There are no duplicate numbers.

• Either smallest or largest number is odd.
  so numbers are
  x,y, y+2, x+7
  and x+y+y+2+x+7 = 31
  2x+2y = 22
  x+y =11
  so checking possibilities, we get
  
  numbers are 5,6,8,12

  Pls check.
  The highest number minus the lowest number is 7.
  As per ur solution, 18-0 =18 and not 7 as per given condition.
