There are 37 palindromic numbers between 1 and 300 (38 if you count from 1 to 300 and include '1'):
2, 3, 4, 5, 6, 7, 8, 9, 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, 212, 222, 232, 242, 252, 262, 272, 282, 292.
actualy this is wrong, single digit numbers aren't palindromic. so there's only 29 palidromic numbers between 1 and 300.
202, 212, 222, 232, 242, 252, 262, 272, 282, and 292 are the palindromic numbers between 200 and 300. NONE of them are prime, since they must all end in 2 they are even and so are divisible by 2, so they are not prime.
There are sixteen prime numbers between 201 and 300.
There are sixteen prime numbers between 201 and 300.
