A population of beetles are growing according to a linear growth model. The initial population (week 0) is P 0 = 3 , and the population after 6 weeks is P 6 = 69 . Find an explicit formula for the beetle population after n weeks. P n = 3(1+11)^n 3 ( 1 + 11 ) n syntax ok After how many weeks will the beetle population reach 333?
