Does the following table represent a geometric sequence or an arithmetic? Explain 

• geometric, it has a constant rate

• geometric, it has a constant percentage

• arithmetic, it has a constant rate

• arithmetic, it has a constant percentage

How is an arithmetic sequence found?

• By multiplying the same number to the previous term. 

• By adding the same number to the previous term.
