Common sense here.
I has to be either 3, 5 or 7.
The number is above 200 so 3 is out. 5 is also out since now we're going into the 300 range, a palindrome that ends with 2 isnt a prime number. So only available option is 7.
I honestly didnt find the real value. Just tried to use common sense and cancelling it out.
