Question
In the sequence 1/2, 1/6, 1/18, what is the common ratio?
1 point
A. 1/3
B. 1/2
C. 3
D. 2
Solution
The common ratio in a sequence is found by dividing any term by the previous term.
In this sequence, if we divide the second term (1/6) by the first term (1/2), we get (1/6) / (1/2) = 1/3.
Similarly, if we divide the third term (1/18) by the second term (1/6), we get (1/18) / (1/6) = 1/3.
So, the common ratio in this sequence is 1/3.
Therefore, the answer is A. 1/3.
