Due to lack of natural predators, the rabbit population of a city park is doubling every year. If the rabbit population is 16 rabbits in year 1, how many rabbits will there be in year 5?

Question

80
256
65,536
1,703,936

Answer 1

To find the number of rabbits in year 5, you need to multiply the initial population by the growth factor each year for 5 years.

Since the rabbit population is doubling every year, the growth factor is 2.

Starting with 16 rabbits in year 1, let's calculate the number of rabbits in each subsequent year:

Year 1: 16 rabbits
Year 2: 16 x 2 = 32 rabbits
Year 3: 32 x 2 = 64 rabbits
Year 4: 64 x 2 = 128 rabbits
Year 5: 128 x 2 = 256 rabbits

Therefore, there will be 256 rabbits in year 5.
