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 618 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 = 618, a2 = 618, a3 = 618, a4 = 618, a5 = 618 B. a1 = 494.40, a2 = 395.52, a3 = 316.42, a4 = 253.13, a5 = 202.51 C. a1 = 618, a2 = 1112.40, a3 = 2002.32, a4 = 3604.18, a5 = 6487.52 D. a1 = 618 , a2 = 494.40, a3 = 395.52, a4 = 316.42, a5 = 253.13
