The explicit rule for any arithmetic sequence is:

a(n)=a+d(n-1), a=initial term, d=common difference, n=term number

In this case a=-3 and d=7 so:

a(n)=-3+7(n-1)

a(n)=-3+7n-7

a(n)=7n-10

Answer:

The answer is that you tutored for 4 hours.

Step-by-step explanation:

There are 6 total squares, so then you must divide 12 by the number of squares (6), to find the value of one square. Then, you would find that one square equals 2 hours, and since you have 2 squares that means that you tutored for 4 hours.

<em>Hope </em><em>it </em><em>helps</em><em>!</em>
