The sales of homes in a new development have been increasing. In January, 8 homes were sold, in February, 12 homes were sold. In March, 16 homes were sold. This pattern continued for the remainder of the year. What is the explicit rule that can be used to find the number of homes sold in the nth month of the year?

A an=−4n+4
B an=4n−4
C an=−4n−4
D an=4n+4

Answer 1

an = 4n + 4
AKA C is the correct answer.

say n is the number of the month after the start of the year

January would be a1 = 4*1 + 4 = 8
February would be a2 = 4*2 + 4 = 12

and so on
