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 662 with r = 0.7. Write a recursive sequence that describes this data, where an  denotes the insect density during year n.

A. an = 0.7 an+1  , a1 = 331
B. an = 0.7 an-1  , a1 = 662
C. an =   , a1 = 662
D. an = 0.7 + an-1  , a1 = 662
