pickupchik [31]

Answer:

$a(n) = 80(3)^{n}$

524880

Step-by-step explanation:

Scarlett bought an ant farm with 80 ants. From the following week forward, the ant population tripled every week.

So, the population of ant after 1st week will be (80 × 3) = 240

Again, after 2 weeks this will be (240 × 3) = 720

Therefore, the ant population is increasing in a geometric sequence and here the first term is 80 and the common ratio is 3.

Hence, if a(n) is the population of ant after n weeks then,

$a(n) = 80(3)^{n}$ (Answer)

Now, there will be $80(3)^{8} = 524880$ ants after 8 weeks. (Answer)
