I'm assuming each glyph has a self contained pattern. This may be a huge coincidence but leave no stone unturned, as it goes.

A few of the numbers are divisible by three.
24/3= 8
18/3= 6
36/3= 12

If this is a simple pattern than the missing number is 10.

19+11=30
30/3= 10

Now that leaves us with 97 and 83.

97-83= 14

or

97+83= 180
