Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 28
Step 1: Observe the pattern
Check row-wise ratios or differences:
- Row 1: 6 → 10 → 14 (difference +4 each)
- Row 2: 9 → 15 → 21 (difference +6 each)
- Row 3: 12 → 20 → ? (difference seems increasing; likely +8 each)
Step 2: Calculate missing number
$12 + 8 = 20 \quad (\text{already given}) 20 + 8 = 28$
