Answer:

The Arithmetic progression formed will be: 7, 12, 17, 22...

a = 7, d = 5

The nth term or an = a + (n-1)d

= 7 + (n-1)5

= 7 + 5n - 5

= 5n + 2

The answer is A. 5n + 2

Hope this helps!

The explicit rule that can be used to find the number of homes sold in the nth month of the year is option A which is 5n + 2.

What is Arithmetic progression?

This is defined as a sequence where the differences between every two consecutive terms are the same.

Arithmetic progression = 7, 12, 17, 22...

a = 7, d = 5

The nth term  = a + (n-1)d

= 7 + (n-1)

= 7 + 5n - 5

= 5n + 2
