What would be the next number in this series 15 12 13 10 11 8?
If you mean: 2 3 5 7 11 13 and 17 then the next number is 19 because they are all prime numbers
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)
2 3 5 7 11 13 17 19 23 29 31 They are prime numbers.

2 3 5 7 11 13 17 19 23 ... Prime numbers
i think the answere is 38

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
26.Add successive odd numbers to get the next number in the list:1+1=2, 2+3=5, 5+5=10, 10+7=17, 17+9=26. The number following 26 would be 37: 26+11=37.
If you eliminate the first number, the rest are prime and the next one would be 29.
If you mean: 2 3 5 7 11 13 and 17 then the next number is 19 because they are all prime numbers
The next number is 17. You're adding 8, and then subtracting 5. So; 2 + 8 = 10 10 - 5 = 5 5 + 8 = 13 etc... 19 - 5 = 14 14 + 8 = 22 22 - 5 = 17
+1, +2, +4, +8 It doubles each time. The next number will be 35.
