This is an arithmetic sequence because each term is 7 greater than the previous term, so 7 is what is called the common difference...
Any arithmetic sequence can be expressed as:
a(n)=a+d(n-1), a=first term, d=common difference, n=term number.
We know a=1 and d=7 so:
a(n)=1+7(n-1)
a(n)=1+7n-7
a(n)=7n-6
The above is the "rule" for the nth term.

Step-by-step explanation:
The answer is 18 are white chocolate.
Here is my proof
4 × 6 = 24 and 3 × 6 = 18 and I got 4 and 3 from the ratio of dark chocolate candies to white chocolate candies and I got the 6 from the multiplication chart that they both end up with the same number which is 6. So 18 is the answer

Step-by-step explanation:
The question has missing details. So, I'll solve using a general assumption.
Let one of the coordinates of the figure be
Let the scale factor be n
When dilated, the new figure is:
To return the image back to the original figure, the new scale factor mus be a reciprocal of the previous scale factor i.e. 
So:
Substitute n(x,y) for A';
Take for instance:
-- scale factor
To get A from A', using the analysis above
