This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped Tutorial Exercise Find a formula for the general term a,, of the sequence, assuming that the pattern of the first few terms continues. 1 2 3 4 9' 16' 25' 36' Part 1 of 5 The fractions in the sequence {- 1 2 9' 16' 25' 36 .) all have denominators that are perfect squares perfect squares Part 2 of 5 The denominators are all perfect squares. When n = 1, the denominator is 9, which is 3 3 2. When n = 2, the denominator is n 4 7 4 2. For the general nith term, the denominator is (-1)n n+ Part 3 of 5 Ignoring the sign, the numerators are 1, 2, 3, 4,.... For the general no term, the numerator is (n + 2)2
