Accepted Answer

A. The middle number is the sum of alphabetical positions ($A=1, B=2, \dots, Z=26$) of all letters in the adjacent triplets: - Row 1: $	ext{EJO} + 	ext{TYE} = (5 + 10 + 15) + (20 + 25 + 5) = 30 + 50 = 80$ - Row 2: $	ext{DHL} + 	ext{PTX} = (4 + 8 + 12) + (16 + 20 + 24) = 24 + 60 = 84$ - Row 3: $	ext{CFI} + 	ext{LOR} = (3 + 6 + 9) + (12 + 15 + 18) = 18 + 45 = 63$
