Question

What are the values of a1 and r of the geometric series?

Answer 1

Answer:

the answer is c on edg

Step-by-step explanation:

Answer 2

A1 or just a as it is in the equations is just the initial term of the sequence.  In this case a1=1

r is the common ratio which is that constant ratio found by dividing any term by the term preceding it...

In this case r=3/1=9/3=27/9=etc=3

So a1=1 and r=3, C. is your answer.
