Question 1134909: Find an explicit rule for the nth term of the sequence.
1, 3, 9, 27, ... (2 points)


an = 1 • 3n + 1

an = 3 • 1n - 1

an = 1 • 3n - 1

an = 1 • 3n

1, 3,+9, 27

if n=0,1,2,3,.....
answer is:
a%5Bn%5D+=+1+%2A3%5En
check
a%5B0%5D+=+1+%2A3%5E0=1
a%5B1%5D+=+1+%2A3%5E1=3
a%5B2%5D+=+1+%2A3%5E2=9
a%5B3%5D+=+1+%2A3%5E3=27
