Official Explanation
Note that answering this question requires information only about the first five terms of the sequence. So it is a good idea to work with the relationships among these five terms to see what is happening. Since you are given that in this sequence each term after is c greater than the previous term, you can rewrite the first five terms of the sequence in terms of \(a_{1}\) and \(c\) as follows.
