First, I wrote down all the options that equalled 15. Next, I checked all of them to see if there was more than one answer. I made sure that I didn't use the same number twice. I found out that the only answer that worked was 6 & 9. The pattern went like this:
6,9,11,12,4,14,7.
There may be more than one answer, but I think it is just this one. I hope my advise has helped. - Soph
