Answer:
Yes, the sequence is arithmetic. The common difference is 1/6.
Step-by-step explanation:
The value of each of the numbers is going down, so we can assume that we are subtracting something.
If you subtract 1/2 by 1/3, you will get 1/6.
1/3 - 1/6 also equals 1/6.
1/6 - 0 also equals 1/6.
So yes, this is an arithmetic sequence and the common difference is 1/6. Hope this helps!
