The numbers keep reducing by 3, so the answer is 8.
14
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 + 14 + 16 + 17 = 58
Think it's 30...then 20
Points: (-11, -17) and (-14, -19) Slope: 2/3
17
17
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.
-3 + 14 = 11
17 + 14 + 17 + 19 + 18 + 13 + 11 = 109
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
14 - 311/17 = 10 + 3 + 1 - 311/17 = 10 + 3 - 3 + 1 - 11/17 = 10 + 0 + 6/17 = 106/17
