add 17 and 15 in the 1st figure you get 32 then add 12 and 8 you get 20 now subtract 32 and 20 you will get 12 which is the middle number. Now apply the same pattern with the 2nd figure when you have applied the pattern you get 50 which is the middle number. Apply pattern in 3rd figure and you get 15
