A sequence has a third term of 18, and a common ratio of 3.
What is the fifth term?
6
486
54
162
The second term of the sequence can be found by dividing the third term by the common ratio:
Second term = 18 รท 3 = 6
Similarly, the fourth term can be found by multiplying the third term by the common ratio:
Fourth term = 18 x 3 = 54
Finally, the fifth term can be found by multiplying the fourth term by the common ratio:
Fifth term = 54 x 3 = 162
Therefore, the fifth term is 162. Option D is correct.
