    $\begingroup$ Welcome to Puzzling. A couple of points, 1) It appears as if your question got cut off... I've attempted to fix it based on the title, but you should review. 2) You may want to have a look at this meta post which includes tips on writing number sequence puzzles. $\endgroup$ – Alconja Oct 8 '17 at 23:05

    $\begingroup$ $15+39+8+49 = 100+11$, seems to have the format $\frac{15}{1} , \frac{39}{1} , \frac{1}{8} , \frac{1}{49}, \frac{100}{1}, \frac{11}{1},\frac{1}{?}, \frac{1}{?}$. So, the last two question marks will sum to $168$? Also $(15-8)^2 = 49, (49-39)^2 = 100$. $\endgroup$ – Carl Löndahl Oct 9 '17 at 20:36
