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 620 with r = 1.9. 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 = 1178.00, a2 = 2238.20, a3 = 4252.58, a4  = 8079.90, a5  = 15,351.81
B. a1 = 620, a2 = 62.00, a3 = 6.20, a4  = 0.62, a5  = 0.06
C. a1 = 620, a2 = 1178.00, a3 = 2238.20, a4  = 4252.58, a5  = 8079.90
D. a1 = 620, a2 = 620, a3 = 620, a4  = 620, a5  = 620
