D Correct answer
Explanation

The pattern is: ×1.5+1.5, ×2+2, ×2.5+2.5, ×3+3, ×3.5+3.5. Checking: 2×1.5+1.5 = 4.5, not 3. 3×2+2 = 8, not 6. 6×2.5+2.5 = 17.5, not 15. The pattern doesn't fit. Alternative pattern: ×1.5+1.5, ×1.5+1.5, ×2, ×2.5+1.5, ×3+1.5. Testing shows inconsistency. The number 46 doesn't fit the expected progression based on the initial pattern structure.
