77
165

Answer is Wrong!
Answer is Right!
The correct answer is $\boxed{\text{C}}$.
The sequence is a simple addition series, with each term being the sum of the previous two terms. Therefore, the sequence should be $6, 15, 35, 77, 122, 221$.
The term $165$ is incorrect because it is not the sum of the two previous terms. The sum of the previous two terms is $77 + 122 = 199$. Therefore, the term $165$ is out of place.
