### How many palindromes are there between 900 - 1900?

For the 3 digit numbers from 900 - 999 then the 1st and 3rd numbers must be 9. The middle digit can vary from 0 - 9 making 10 palindromes in this range. For the 4 digit numbers from 1000 to 1900 then the 1st and thus the 4th digit can only be 1. The middle pair of digits must be identical and can vary from 00 to 88 making 9 palindromes in this range…

### What years between 1 and 1964 are palindromes?

### How many palindromic numbers are there between ten and hundred thousand?

1089. Explanation A two digit palindrome will have the form AA, with A a digit between 1 and 9 (if A were zero, then this would not be a two digit number). So there are 9 possibilities for A and nine two-digit palindromes. A three digit palindrome will have the form ABA, with A a digit between 1 and 9 (if A were 0, this would not be a three digit number) and B a…

### How many 5 digit palindromes are there?

900 This explains it. A positive integer is a palindrome if it reads the same forward and backwards such as 1287821 and 4554. Determine the number of 5-digit positive integers which are NOT palindromes. We start by counting the total number of 5 digit positive integers. The first digit is between 1 and 9, so we have 9 choices. Each of the other 4 digits can be anything at all (10 choices for each). This…

### How many palindromes between 1000 and 3000?

A palindrome reads the same forwards as backwards. Therefore the first and last digits must be the same, the second and penultimate the same, and so on. As 1000 & 3000 both have 4 digits, there are two pairs of digits that must be the same: the first and fourth, the second and third. The first digit (and hence last digit) can only be 1 or 2 - a choice of 2 The second digit…

### 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

### What day was the 1st 2002?
