The common difference between terms in an arithmetic sequence is the constant value that is added (or subtracted) to each term to obtain the next term.

In the given sequence 14, 8, 2, -4, …, we can see that each term is obtained by subtracting 6 from the previous term.

The common difference is therefore -6.

The correct answer is A. Yes, -6.
