INTEREST Kordell opened a savings account with $1200 that earns 14% simple
interest. Because simple interest is based on the principal deposit, the interest

account each year can be represented by an arithmetic sequence.
a. Write the balance of the account after each year as a sequence.
b. Write an equation to represent the sequence.
