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
11 comes next.
13
10 4 3 11 15 9 8 16 20....
2

The pattern is - 5 then +2. 2 and 4 are the next numbers in the series.
11 because 4+1=5 3+5=8 2+8=10 1+10=11 0+11=11
