What is the rescursive formula for this geometric sequence? 7, -14, 28, -56

In a certain pentagon, the interior angles are a, b,c, d,e where a, b,c, d,e are integers strictly less than 180. ("strictly less than 180" means they are "less than and not equal to" 180.) if the median of the interior angles is 61 and there is only one mode, then what are the degree measures of all five angles?

Give the equations of two different lines that are perpendicular to the line 3x + 4y = 7.
