Question

Number missing in sequence 29 38 3 8 14 ?

Answer 1

15.  I arrived at this conclusion because of the following:

29, 38 The difference is 9 between 29, and 38.
3, 8 The difference is 5 between 3, and 8. 
14, 15 The difference is 1 between 14, and 15.
The pattern is 9-4= 5 and 5-4=1
So I have 9, 5, 1, a difference of 4.
