Exploring Geometric Sequences and Exponential Functions

What is a geometric sequence?

• A list of numbers without any specific order

• A list of numbers where each term is divided by a constant

• A list of numbers where each term is multiplied by a constant

• A list of numbers where each term is added by a constant

How is a geometric sequence expressed as an exponential function?

• a_n = a_1 * r^(n-1)

• a_n = a_1 + r^(n-1)

• a_n = a_1 / r^(n-1)

• a_n = a_1 - r^(n-1)
