Create your own real-world problem which uses either an arithmetic or geometric sequence to solve it. include the solution, with work and explanation, to your problem.

Step-by-step explanation:

The amount of bacteria in a researcher's dish increases at a rate of 4,000 more than the previous amount every second. The starting amount of bacteria is 500,000, how many bacteria will there be in 5 seconds?

a(n) = 500,000 + 4,000 x n - 1

a(n) = 500,000 + 4,000 x 4

a(n) = 500,000 + 16,000

a(n) = 516,000 bacteria in 5 seconds

seconds  bacteria

1             500,000

2            504,000

3            508,000

4            512,000

5            516,000

As you can see, both lead to the correct answer, which shows us we set up the formula correctly.
