2 -> 9 = +7
9 -> 5 = -4
5 ->13 = +8
13 -> 10 = -3
10 -> 19 = +9
19 -> 17 = -2
As you can see, every other time, the number is increased. It was originally increased by 7, then 8, then 9. So, the next number should be increased by 10 = 27
The number which best completes the sequence below is:2 9 5 13 10 19 17?
