15 + 23 = 38 1/5 + 2/3 = 3/15 + 10/15 = 13/15

There are 3 different magazines for a Glock 23- 10 CARTRIDGES (not bullets) or 13 or 15.
It is smaller by 10 because 23-13 = 10
11, 13, 15, 17, 19, 21, 23
Because of the pattern of plus 11 then minus ten I would go with 13 24 14
10 18 15 23 20

13 x 23 x 19 x 15 = 85215
(17-4)+10=23 13+10=23
