# Are there more 11 digit or 12 digit palindromic numbers?

There are the same number: any twelve digit palindrome is just
an eleven digit palindrome with its central digit repeated. In
general, if we are considering numbers of *n* digits: For even
values of *n*, the number of palindromes is 9 x 10n/2 - 1 For
odd values of *n*, the number of palindromes is 9 x
10(n-1)/2
