Bryce started with $450 in a bank account that does not earn interest. In the middle of every month, he withdraws 13 of the account balance.


Which recursive function rule models Bryce’s balance at the end of each month?




an=23⋅an−1 and a1=450


an=450⋅an−1 and a1=23


​ an=13⋅an−1 ​ and a1=450


an=450⋅an−1 and a1=13

Verified Answer :

because bryce started off with $450 ,  then his a1 should be $450. Then the amount of money that he will have after one month is 
an = 13(an-1)
In this case, an is the amount of money he has and an-1 is the amount of money he has in his account from the month prior
