Sorry, that's incorrect. Although you are correct that the weekly attendance is greater than 4,500 in week 6, this is not the first week in which this occurs.
The student may have misinterpreted the question, and selected any week for which the attendance is greater than 4,500, rather than the first week for which the attendance is greater than 4,500. It is also possible that the student has an incomplete understanding of how to generate successive terms in a geometric sequence.
