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 692 with r = 0.6. 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 = 415.20, a2 = 249.12, a3 = 149.47, a4 = 89.68, a5 = 53.81 B. a1 = 692, a2 = 1107.20, a3 = 1771.52, a4 = 2834.43, a5 = 4535.09 C. a1 = 692, a2 = 692, a3 = 692, a4 = 692, a5 = 692 D. a1 = 692 , a2 = 415.20, a3 = 249.12, a4 = 149.47, a5 = 89.68
