Question 132071: What number is next in this series? 10, 4, 3, 11, 15 . . .
I chose 14 because 10-4=6; 4-3=1; 3-11=8; 11-15=4; 15-14=1. The series appeared to me to be even, odd, even, even, odd. Is 14 the correct answer?

I don't see any pattern. And I don't understand how you obtained 14. One possible solution is 2, derived by the difference between 10 and 4 is 6. Half of 6 is 3, which is the 3rd number. Then the difference between 11 and 15 is 4. Half of 4 is 2 which might be the next number. I don't really see a series out of this, however.
