What is the 23rd term of the arithmetic sequence where a1 = 8 and a9 = 48?

yKpoI14uk [10]

$a_1=8$
$a_2=a_1+d=8+d$
$a_3=a_2+d=(8+d)+d=8+2d$
$a_4=a_3+d=(8+d)+2d=8+3d$
...
$a_9=8+8d=48\implies d=5$
$a_{10}=8+9d$
...
$a_{23}=8+22d=118$

which of the following best describes a regular polygon when the measure of each exterior angle is 36 ?

zhenek [66]

Even though you have no choices listed:

Each Exterior Angle = Each Central Angle = (360 degrees) ÷ (Number of Sides)
Each Exterior Angle = (360 degrees) ÷ (Number of Sides)
(Number of Sides) = 360 / 36
Number of Sides = 10
