## Week 2-Geometric sequences

categories: Math 11

This week we learned about geometric sequences and series. A Geometric sequence differs from an arithmetic sequence because instead of adding a common difference, a common ratio is multiplied by the term to get the next term.

the equation used to find a term in a sequence is

in this equation is represented by

for example: 5,10,20,40… find

A finite geometric series can be found using the equation
