A palindromic word or sentence is one that reads the same both forwards and backwards, e.g. "Able was I ere I saw Elba". By extension a palindromic number could be one that reads the same both forward and backward, e.g., 101, 202, etc.
A number when read from front to back means the same than that number s called a palindrome.
for eg:- Palindrome:- 1001 as reverse is 1001
Non Palindrome:- 5688 as reverse is 8865
A palindrome number is one that reads the same from left to right or right to left.
Numbers that read the same backwards and forwards. 1001, 343, 20602
There are 90 palindromic numbers.
There are not just 13 non-palindromic numbers. Most numbers are non-palindromic.
There are 90 palindromic numbers between 100 and 1000
No.
Nobody went out to create them: some numbers simply happen to be palindromic and others don't.
No.

there are 10 palindromic numbers between 9000 and 10000 9009,9119,9229,9339,9449,9559,9669,9779,9889,9999!!!
As 20569.8 is not palindromic, any number that is like it must contain that property and similarly be non-palindromic, so no.
I guess that the smallest would be zero, if you don't consider negative numbers. There is no largest palindromic number - you can make them as large as you like.
