@Roshinireddy.
So divide the list into a pair of 3 values each.
First, we get 28, 25, 5.
So for this 28-25 = 3 which is our main difference. Now they have put 5 randomly here without any logic.
The second pair is 21, 18, 5.
For this 21 -18 = 3 which is again our main difference and put 5 randomly after this.
