The next numbers are 27 and 26 and 37.
The sequence is:
2 to 9 = add 7
9 to 5 = subtract 4
5 to 13 = add 8
13 to 10 = subtract 3
10 to 19 = add 9
19 to 17 = subtract 2
So the next 3 steps are:
add 10 = 27
subtract 1 = 26
add 11 = 37
The next number in the sequence is 27.
that best completes the sequence 2 9 5 13 10 19 17 is 27.
The number after 17 is 27. 2+7 = 9 9 - 4 = 5 5 + 8 = 13 13 - 3 = 10 10 + 9 = 19 19 - 2 = 17 17 + 10 = 27
