This is a geometric sequence with first term 2 and common ratio 5.
an = a1 r^(n-1) IS THE GENERAL FORM SO HERE IT IS:-
an = 2(5)^(n-1)
Answer:
Step-by-step explanation:
The first part is already solved.
<u>We got the scale factor </u>
<u>Use this to find the missing side:</u>
The answer is 72°
18 x 2 = 36°
180 - 36 = 144°
144 / 2 = 72°
