Answer:
C a1= -2
an = an-1 +3
Step-by-step explanation:
an = -2+ (n-1)3
What is the first term? Let n=1
a1 = -2 + 0*3
a1 = -2
The difference between the terms is +3 (coefficient on (n-1))
The second term is the first term +3
The third term is the second term plus 3
The next term is the previous term +3
so an = an-1+ 3

The small sign's perimeter is 36 inches
Step-by-step explanation:
The scale factor between two figures is obtained by:
So,
We know that
Putting the values in the above equation of scale factor we get
Cross multiplication
Dividing both sides by 5
Hence,
