The pattern seems to be 16^2 plus 29 = 285
285
27 is not a prime number.
19 23 29 31 and so on. All prime numbers
A prime number is a number that is divisible only by 1 and itself; it has no other factors. The factors of 7 are 1 and 7. The factors of 13 are 1 and 13. The factors of 27 are 1, 3, 9, and 27. The factors of 29 are 1 and 29. Therefore, 27 is the only one that is not a prime number.

Actually the next number in the sequence is 17 A 19 , 23 , 29 , 31 ,.......... Prim number
The next number in the sequence 5-7-13-31 is 69.
This is a list of prime numbers, the next ones are 17, 19, 23, 29
42 is the next number in this sequence. This number sequence is adding the next prime number to the last number. So 1 + 2 = 3. Then 3 + 3 = 6, 6 + 5 = 11, 11 + 7 = 18, 18 + 11 = 29. The next prime number after 11 is 13, so 29 + 13 = 42. The next numbers would be 59 (42+17), 78 (59+19), and 101 (78+23)
If you eliminate the first number, the rest are prime and the next one would be 29.
2 3 5 7 11 13 17 19 23 29 31 They are prime numbers.
