The sales of homes in a new development have been increasing. in january, 7 homes were sold, in
february, 12 homes were sold. in march, 17 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?
• an = 5n + 2
an = 5n - 7
an = 5n - 2
an = 5n +7

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!

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
