a (sub n) = 11 + (n - 1) x d
The pattern is subtract 9, add 3. 26-9 = 17 17+3 = 20 20-9 = 11 11+3 = 14 14-9 = 5 So, 5 +3 = 8

11 and 8
a (sub n) = 11 + (n - 1) x d
20 - (3 * (n - 1))
The nth term is: 3n+2 and so the next number will be 20
The pattern is subtract 9, add 3. 26-9 = 17 17+3 = 20 20-9 = 11 11+3 = 14 14-9 = 5 So, 5 +3 = 8
20 + 3 = 23 23 + 5 = 28 28 / 2 = 14 14 + 3 = 17 17 + 5 = 22 22 / 2 = 11 11 + 3 = 14 14 + 5 = 19 19 / 2 = 9.5

10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20
12 11 18 14 24 17 30 20.. i think ;-) pattern: 18-12 = 6 14-11 = 3 24-18 = 6 17-14 = 3 i hope that helps.
