The sequence interval is 2 4 6 8 ( this is the difference of number). so the missing number is -1 if I'm not mistaken.
The first number in the sequence 19, 23, 29, 31 is 19. This sequence lists prime numbers, and 19 is the smallest among them.
29
17, 19, 23, 29, and 31
If you mean: 41, 29, 35 and 23 then they are all prime numbers except for 35 which is a composite number.

-47, -41, -35, -29, -23, -17, -11, -5, 1, etc.
The first Prime number after 23 is 29.
23 and 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)
The first prime number after 23 is 29.
It is 23 followed by 29
