Answer from: tishfaco5000

Initial population of Rabbit = 5 rabbit

After 2 months

Population of Rabbit = 10

After 4 months

population of rabbit = 20

Formula for growth is :

G = $G_{0}[1 + R]^n$ , where G is final population and $G_{0}$ is initial population, and R is growth rate.

1. 10 = 5 [1 +R]²

Dividing both sides by 5 , we get

2 = (1 + R)²

→ R + 1 = √2 ⇒ taking positive root of 2

→R = √2 -1

Amount of rabbit after 1 year = $20(1 + \sqrt2 -1)^8= 20 \times (\sqrt2)^8= 20 \times 2^4= 20 \times 16= 320$

Answer from: kimsouther2

The amount of rabbits after 1 year is $\boxed{635}$ .

Further explanation:

The terms of the geometric sequence can be written as,

$a,ar,a{r^2},a{r^3}$ , ..

Here, is the first term and is the common ratio.

If the first term and the second term is known then, the value of can be obtained.

Now, the value of any term can be easily obtained with the help of a and r.

Explanation:

The initial population of the rabbit is 5.

After two months the population of the rabbit is 10.

After four months the population of the rabbit is 20.

After six months the population of the rabbit is 40.

After eight months the population of the rabbit is 80.

After ten months the population of the rabbit is 160.

After twelve months the population of the rabbit is 320.

The series can be formed as,

$5,{\text{10, 20, 40, 80, 160, 320}}$

Now find the sum of all the population.

$\begin{aligned}{\text{Sum}} &= 5 + 10 + 20 + 40 + 80 + 160 + 320\\&= 685 \\\end{aligned}$

The amount of rabbits after 1 year is $\boxed{635}$ .
