Take first three number as one set. Then take second three number as another set. Here end number these two set is 5. So just leave. Then you have first set as 28 25.

Second set as 21 18.

Here the difference between First number from first set and first number from second set is 7.

Here third set first number is available as 14, then 18-7=11.

Add 5 as last number. Now answer is 14, 11, 5.
