The measures of the interior angles of a convex polygon are in arithmetic progression. If the smallest angle is 105° and the largest angle is 135° then find the number of sides of the polygon. => 6 or 5 or 8 or 7..

The sum of n terms of an Arithmetic Progression, S n , is given by the formula S n = n 2 ( a + l ) , where a is the first term and l is the last term of the A.P. Find the first term of the A.P if its last term is 79, and the sum of 9 terms is 396? => 11 or 9 ..
