Assume the following sequence is arithmetic: 4, 12, …. Write an equation (rule) for this arithmetic sequence.

I am not sure exactly what the question is asking...

12 - 4 = 8, so the difference between 4 and 12 is 8.

If you were to keep writing the sequence it could go like this, “4, 12, 20, 28...” and so on, adding 8 every time.

Let me know if you need any more help!
