Tutorial Exercise Find a formula for the general term a, of the sequence, assuming that the pattern of the first few terms continues. (41 1 1 1 9' 71' 13' 15) Part 1 of 3 The fractions in the sequence . 1 19: 15: " all have a denominator which is odd V odd Part 2 of 3 The denominators are all odd. For example, when n = 2, the denominator is 9 9 when n = 3, the denominator is 11 11 Part 3 of 3 Formulas for the ath odd number are either 2n + k or 2n - k, where k is an odd number. In order for n to start from 1, the nth term should be written as a, = 2n - 1 Submit Skip (you cannot come back)
