Explanation:

We have,
The given sequence = 5836   7469   8251   6293   4172
After interchanging first digit with second digit and third digit with fourth digit, we get:
8563   4796   2815   2639   1427
Now, interchanging first and fourth digit of each of the above number, we get:
3568   6794   5812   9632   7421
Here, the highest and second lowest numbers are ‘9632’ and ‘5812’
Required Difference = 9632 – 5812 = 3820
