An animal reserve has 42,000 elk. The population is increasing at a rate of 16% per year. How long will it take for the population to reach 84,000?

4.67 years

Step-by-step explanation:

The future population is calculated by where A is projected population, P is present population, i is interest rate in decimal and n is duration in years.

a_n = a_1 + (n - 1)d

the first term is 6.

the common difference d = ?

when you find d, replace n with 7 and d with the common difference to find your answer.
