Answer:
If the interior angle is 168, then the exterior angle is 180 - 168, or 12. The 360 degrees is evenly distributed over all of the angles, so 360/12 = 30 sides. The formula for the sum of the angles in an n-sided polygon (in degrees) is 180(n-2).

The geometric rule for the nth term of the geometric sequence for which a1 =−6 and a5=−486 is -6 × 3^(n - 1)
<h3>The nth term of a geometric sequence</h3>
First term, a1 = -6
Fifth term, a5 = -486
a5 = ar^(n - 1)
-486 = -6 × r^(5-1)
-486 = -6r⁴
r⁴ = -486 / 6
r⁴ = 81
r = 4√81
r = 3
Geometric rule:
nth term = ar^(n-1)
nth term = -6 × 3^(n - 1)
