Some Quick Palindrome Math

A car's odometer shows 72927 miles, a palindromic number. What are the minimum miles you would need to travel to form another?

A palindrome is a word (or in this case a number) which can be read forwards and backwards as the same word, such as kayak or 1221.


  1. The next one would be 73037, I would think. So, 110 miles?

  2. I got 110 too, is this correct?

  3. I believe so. 73,037 should be the next palindrome mile, so the car has to go 110 miles to get there.
