Answer:
1/4
Step-by-step explanation:
The common ratio of a geometric sequence is the number that is multiplied to get the next term in the sequence.
We can see that the numbers decrease:
32, 8, 2, 1/2, ...
To get from 32 to 8, we would divide by 4. Dividing is the same as multiplying by a fraction; this means that dividing by 4 is the same as multiplying by 1/4. Thus 1/4 is the common ratio.
