Which term of the sequence –3, 1, 5, 9, 13, … is 65? Alisha solved the question as shown below. an = 65 a1 = –3 d = –3 – 1 = –4 65 = –3 + (n–1)(–4) 65 = –3 –4n + 4 65 = 1 – 4n 65–1 = 4n n = 64 ÷ 4 n = 16 So, the 16th term of the sequence is 65. What is the error in the computation? Find the correct answer.

Jamie is hiking up a small mountain. he climbs up at a constant rate of 300 feet/hour until he reaches the peak at 1,500 feet. after that, he hikes down at the same rate to the base of the mountain. the equation that models jamie’s elevation, e, after t hours is e = . jamie’s elevation will be 600 feet after hours and after hours.
