To find the common difference of an arithmetic sequence, we subtract any two consecutive terms in the sequence.
Let's calculate the common difference using the first two terms, -9 and -10:
-10 - (-9) = -10 + 9 = -1
Now, using the second and third terms, -10 and 1/2:
1/2 - (-10) = 1/2 + 10 = 10.5
Since we have obtained two different results, -1 and 10.5, it means that the given sequence is not an arithmetic sequence.
