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 622 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 = 622, a2 = 622, a3 = 622, a4 = 622, a5 = 622 B. a1 = 622, a2 = 995.20, a3 = 1592.32, a4 = 2547.71, a5 = 4076.34 C. a1 = 622 , a2 = 373.20, a3 = 223.92, a4 = 134.35, a5 = 80.61 D. a1 = 373.20, a2 = 223.92, a3 = 134.35, a4 = 80.61, a5 = 48.37
