A three-digit palindromic number is a number that reads the same forwards and backwards, consisting of three digits. These numbers take the form ( aba ), where ( a ) is any digit from 1 to 9 (to ensure it's a three-digit number), and ( b ) is any digit from 0 to 9. Examples include 101, 121, 131, and so on, up to 999. There are a total of 90 three-digit palindromic numbers.
Palindromic numbers between 100 and 600 are those that read the same forwards and backwards. The three-digit palindromic numbers in this range are 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, 212, 222, 232, 242, 252, 262, 272, 282, 292, 303, 313, 323, 333, 343, 353, 363, 373, 383, 393, 404, 414, 424, 434, 444, 454, 464, 474, 484, 494, 505, 515, 525, 535, 545, 555, 565, 575, 585, and 595. There are a total of 49 palindromic numbers between 100 and 600.

To be a 3 digit palindromic number, it must be of the form aba.I assume that a 3 digit number must be at least 100 (so that 020 for example does not count as a 3 digit number):a can be any of the nine digits 1-9;for each of these b can be any of the ten digits 0-9Thus there are 9 x 10 = 90 three digit palindromic numbers.
Palindromic numbers between 100 and 600 are those that read the same forwards and backwards. The three-digit palindromic numbers in this range are 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, 212, 222, 232, 242, 252, 262, 272, 282, 292, 303, 313, 323, 333, 343, 353, 363, 373, 383, 393, 404, 414, 424, 434, 444, 454, 464, 474, 484, 494, 505, 515, 525, 535, 545, 555, 565, 575, 585, and 595. There are a total of 49 palindromic numbers between 100 and 600.
