Grid (row-wise):
(72, 24, 6)    (96, 16, 12)    (108, ?, 18)

Pattern: In each row, $$\text{third} = 2 \times \frac{\text{first}}{\text{second}}$$

Check Row 1: \( 2 \times \frac{72}{24} = 2 \times 3 = 6 \) ✅
Check Row 2: \( 2 \times \frac{96}{16} = 2 \times 6 = 12 \) ✅

Apply to Row 3: Let the missing number be \(x\). $$18 = 2 \times \frac{108}{x}  $$

$$\;\Rightarrow\;18= \frac{216}{x}  $$

$$\;\Rightarrow\; x = \frac{216}{18} = 12$$

Missing Number: 12

Answer: Option 1
