Course Description

In the laboratory, under favorable conditions, a growing bacterial population doubles at regular intervals. What will be the total count of bacteria after a known amount of time?

Interest is added at the end of each month, just before the payment is made. How much should be paid each month? Knowledge of Sequences and Series helps us in answering questions like these.
