7 and 1
The numbers are 7 and -5 because 7-(-5) = 12 and 7+(-5) = 2
7 and 2 are the prime numbers having a difference of 5.
The difference between the numbers is increasing by 1 every time. Therefore, since the difference between the last two numbers is equal to 6, the difference between the next two numbers will be 7. 20 + 7 = 27. Therefore the next number in the sequence will be 27.
