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
This is a list of prime numbers, the next ones are 17, 19, 23, 29
The next number in the sequence 5-7-13-31 is 69.
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.
