Solve the Problem n\mathrm { n } Can Be Modeled by the Recursively Defined Sequence

Question 336

Multiple Choice

Solve the problem.
-Suppose that an insect population density, in thousands, during year n\mathrm { n } can be modeled by the recursively defined sequence: a1=1;an=2.79an10.15an12a _ { 1 } = 1 ; a _ { n } = 2.79 a _ { n - 1 } - 0.15 a _ { n - 1 } ^ { 2 } for n>1n > 1 .
Use technology to graph the sequence for n=1,2,3,,20n = 1,2,3 , \ldots , 20 . Describe what happens to the population density function.


A) The insect population stabilizes near 8.738.73 thousand.
B) The insect population stabilizes near 12.8612.86 thousand.
C) The insect population increases every year.
D) The insect population stabilizes near 11.9311.93 thousand.
