Since the given sequence is not described, it is impossible to provide an exact expression for the nth term. However, we can observe that each of the answer choices has a different value for the fourth set of digits in the second set of hexadecimal digits. The correct answer must have a value that increases by 1 for each successive term. Choice B is the only one that satisfies this condition, as the fourth set of digits in the second set of hexadecimal digits starts with 6b0c and increases by 1 for each successive term.
