Please help. I do not have any idea about how to get started on this or finish it.
I was told that the answer that I got was not the complete answer that was needed for me to submit. I do not understand how to extend the problem. I am not able to follow the pattern. This is only one out of 18 problems that I am asking for help with. Please help if you can.
Thank you
