1. Desert Soils
2. Dunes and Associated Soils
3. Brown Soils
4. Sierozems
5. Red Loams
6. Hill Soils (Lithosols)

Logic: second Number = First Number × 2 + 1

Third Number = First Number ÷ 2 + 1

(56, 113, 29) → 56 × 2 + 1 = 113, 56 ÷ 2 + 1 → 29

(68, 137, 33) → 68 × 2 + 1 = 137, 68 ÷ 2 + 1 → 35 ≠ 33

( 72, 145, 37) → 72 × 2 + 1 = 145, 72 ÷ 2 + 1 → 37

(84, 169, 43) → 84 × 2 + 1 = 169, 84 ÷ 2 + 1 → 43
