The correct answer to this problem would be -3. Based on the points you've provided on the graph, -3 would be the correct common difference. :)
Each pair of interior angle and the exterior angle
So the exterior angle = 360° - the interior angle.
4x + 2 < 14
4x < 14 - 2
4x < 12
x < 12/4
x < 3
S = { x <3 }
19/8 is the improper fraction of 2 3/8.
