SOLUTION: A population of beetles are growing according to a linear growth model. The initial population (week 0) is P0=9, and the population after 7 weeks is P7=58. Find an explicit form

Question 1183133: A population of beetles are growing according to a linear growth model. The initial population (week 0) is P0=9, and the population after 7 weeks is P7=58.
Find an explicit formula for the beetle population after n weeks.
Pn =

After how many weeks will the beetle population reach 149?
