1) x is a prime number greater than 2.
Test 3,5. Remainders when divided by 3^2/6 =9/6=3 remainder
5^2/6= 25/6= 1 remainder
Not sufficient
2) x is an odd number 3,5,7,9....
Not sufficient
Taking 1&2 together
3&5 both are odd and prime and the remainders when divided by 6 are different in both cases.
So still not sufficient.
