List prime numbers {2,3,5,7,11,13,17,19,23,29,31}
See if there is difference of 4 between any numbers, since as we move further along the number line the probability of finding a prime number decreases we are most likely to find two prime numbers with a difference of 4 early on in the number line rather than later.
Certainly 3 and 7 as well as 7 and 11 fits the bill
also check 2>p/n>1.5
correct option would be 7 and 11 where 11 would be P

Any other way to solve this with algebra?
