9-1 Independent Practice 8: Application A. For each sequence, write the next four terms. 1. 4,8,16,32, , , , ,... _75635543 a a a 5'" 4. 1,4,13,40, B. The following sequences are defined by recursion formulas. Write the rst four terms of each sequence. 5. a1 = 9; an = 3a,?1 6. a1 = 5;an = ZaH + 7 1 7. a1=100;an =aH +4 8. a1 = 0m\" = 5am1 +3 C. For each of the following sequences, determine the recursion formula. 9. 10,22,46,94,... 10. 18,9,4.5,2.75,... D. Scientists have developed a recursion formula to determine the number of insects in a given population for each interval, n, of time, an = kan_1(1an_1), where k is a constant called the Malthusian factor. 11. Assuming n is measured in weeks, calculate the insect population for weeks 2, 3, and 4 if the initial population is 112, and the Malthusian factor for this population is -9.5. 12. Assuming n is measured in years, and the Malthusian factor for a species of insects is -1, what is the population in year 9 if the population in year 10 is 200
