The pattern is increasing by 6 every term but, initially decreases by 3 (6-3=3)
Let n=term#
Therefore, the pattern rule would be 6n-3, opposed to simply 6n.
To find the 25th term
6(25)-3=
150-3=
147
The 25 term would be 147.
Hope this helped!
Answer:

Step-by-step explanation:
Answer:
- The sum of the eight interior angles not adjacent to these exterior angles is 1280°.

<h2>Given </h2>
- A 15-sided polygon with sum of 7 exterior angles 200°.
<h2>To find </h2>
- The sum of the 8 interior angles, remote to known 7 angles.
<h2>Solution</h2>
<u>We know that:</u>
- sum of all exterior angles of a polygon is 360°.
- sum of each interior and exterior angle pair is 180°.
So the sum of the 8 exterior angles is:
Sum of both interior and exterior angles of 8 angles:
Sum of those 8 interior angles is:
Answer:
180°
Step-by-step explanation:
the 3 interior angles of a triangle add up to 180°
X+ 77.5 because if you subtract 25 from 180 you get 155. Then divide 155 by 2 and you get 77.5
