131?
Yes.
yes
Any number that reads the same forwards and backwards, like 33 or 45654.
The series is a "numerical palindrome" -- the first half of the series mirrors the second half in reverse.

The word form e.g. (Anna or radar) are known as palindromes (singular = palindrome) or palindromic words. The same name is used for numbers that are the same in reverse but are often referred to as 'numerical palindromes' or 'numerically palindromic values'. The use of the word 'numerical' or 'numerically' in relation to a numerical palindrome is not really necessary as being palindromicity, or the nature of being palindromic does not expressly refer to word forms.

Sure. Anything that can repeat in a mirror image sort of a way can be a palindrome. See this page for more information on numerical palindromes:http://www.jasondoucette.com/worldrecords.html
No, not necessarily. 121 is a palindrome number with 3 digits (odd) and is divisible by 11. So this satisfies the premise, but 101, 111, 131, etc are not divisible by 11.An example which satisfies the premise does not prove it true, but one which contradicts the premise is enough to prove it false.
"Aha" is a palindrome that can be used as a preposition.
