They are 13 and 19 which are prime numbers
The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
19
13
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
prime numbers
To find the pattern, simply look for the difference in the first two numbers, then the following pair of numbers, etc. 2 9 5 13 10 19 17 2 + 7 = 9 9 - 4 = 5 5 + 8 = 13 13 - 3 = 10 10 + 9 = 19 19 - 2 = 17 The pattern is +7, -4, +8, -3, +9, -2...

What would be the next number in this series 15 12 13 10 11 8?
From the pattern (n + 4, n + 2, n + ?) I would say the next following number is 20 (n + 1).
Oh, dude, halfway between 13 and 25 is like... 19. Yeah, it's like right in the middle there. You know, like if you were walking from 13 to 25, you'd stop at 19 for a little breather before continuing on.
