↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓ ↓
Z Y X W V U T S R Q P O N
26 25 24 23 22 21 20 19 18 17 16 15 14
THE LOGIC FOLLOWED HERE IS;
1) SWDZ,
S → (+4) → W → (+7) → D → (-4) → Z
2) RVGC,
R → (+4) → V → (+11) → G → (-4) → C
3) FJQM,
F → (+4) → J → (+7) → Q → (-4) → M
4) GKPL,
G → (+4) → K → (+7) → P → (-4) → L
Thus, RVGC is the odd one.
