I took a certain 3-digit number, reversed it, got another 3-digit number, and added the two.
The sum was not a palindrome.
I repeated the process, which resulted in another 3-digit number that was still not a palindrome.
Repeating the process twice more I got a 4-digit number, which was a palindrome finally.
What was the 3-digit number we started with the second time?
(In reply to re: computer findings (spoilers)
Aha; very good. I wasn't thinking of the reversed value itself, that 082 or 092 was not really a 3-digit number.
I've changed my comment from Solution to Some Thoughts.
