Solve the problem.The annual population density of a species of insect after n years is modeled by a sequence. Suppose that the initial density of insects is 644 with r = 0.8. Write a recursive sequence that describes this data, where an denotes the insect density during year n.Find the terms a1 , a2 , a3 , ...., a5 . Round to two decimal places, if necessary.
A. a1 = 644, a2 = 1159.20, a3 = 2086.56, a4 = 3755.81, a5 = 6760.45 B. a1 = 515.20, a2 = 412.16, a3 = 329.73, a4 = 263.78, a5 = 211.03 C. a1 = 644 , a2 = 515.20, a3 = 412.16, a4 = 329.73, a5 = 263.78 D. a1 = 644, a2 = 644, a3 = 644, a4 = 644, a5 = 644
