First I wrote down all the possibilities for each clue. Next I started to put them in order by starting with the first clue possibilities. I wrote down all of these and began going through each clue until I got to a point where the sequence didn't work. If it was incorrect I did a cross at the bottom of the list. I did this for each clue.

In the end I found two solutions...
6,9,11,12,4,14,7 and
8,7,13,10,6,12,9

I did this in an ordered and efficient way to get my results
