The interior angles of a convex polygon of 9 sides are in an arithmetic progression. If the measure of the smallest interior angle is 112, then what is the measure of the largest interior angle?
----------
The sum of the 9 angles is 1260 degs
--> the 4th angle = 1260/9 = 140 degs
140 - 112 = 28
140 + 28 = 168 degs - the largest angle
