Hmm, when a student needs an answer in a hurry, it's a red flag to tutors that it's a test question. The second line is the rule to find the next entry (a_n+1) assuming you know a_n. I'm not sure if it's (5/an) + 4 or 5/(an + 4). For example, a2 = 5/a1 + 4 = 5/3 + 4 = 5 2/3. a3 = 5/a2 + 4, etc. Just follow the rule and you can get all of the values.
