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
Since they are vertical they are equal to each other.
3x + 4 = 7x - 9
4 = 4x - 9
13 = 4x
3.25 = x
So the value of x is 3.25.
Hope this helps :)
