In this set of exercises, you will use sequences to study real-world problems. A cell divides into two cells every hour. (a) How many cells will there be after 4 hours if we start with 10,000 cells? (b) Is this a geometric sequence or an arithmetic sequence? (c) How long will it take for the number of cells to equal

Key Concepts

Arithmetic Sequence

An arithmetic sequence is a sequence of numbers in which each successive term is derived by adding a constant value to the previous term. This concept represents linear growth, in contrast to exponential growth, and is used to describe situations where changes occur by consistent additive amounts rather than multiplicative factors.

Exponential Growth

Exponential growth describes a process in which a quantity increases by a constant multiplicative rate over equal time intervals, leading to rapid increases as time passes. In contexts such as cell division, where each cell splits into two, this concept helps to model how populations grow exponentially over time.

Geometric Sequence

A geometric sequence is a series of numbers where each term is found by multiplying the previous term by a fixed constant, called the common ratio. This concept is fundamental when examining repeated multiplication processes, such as the doubling of cells, and distinguishes this type of sequence from others that use a constant difference.
