When the town of Bradyville first started its voluntary recycling program, 1500 of the town’s residence participated. The town predicts that the number of people participating in the recycling program will increase by 15% each year.

Which explicit rule can be used to determine the number of people participating in the program in the fifth year?

 

an=1500(0.15)^n−1

an=1500(1.15)^n

an=1500(0.15)^n

an=1500(1.15)^n−1

 

 

The explicit rule for a sequence is an=7(−4)^n−1

What is the recursive rule for the sequence?

 

an=−7(an−1),   a1=4

an=−7(an+1),   a1=4

an=−4(an−1),   a1=7

an=−4(an+1),   a=7

First one :

an  = 1500 (1.15)n-1

 

Second one....note the terms

7 (-4)n-1

 

7, -28,  112 , -448, etc...

 

an   =  -4 an-1  , a1  = 7

 

cool cool cool
