Answer: 21
Explanation Step 1: Find the differences between consecutive terms 66 → 63 → difference = 66 − 63 = 3 63 → 57 → difference = 63 − 57 = 6 57 → 45 → difference = 57 − 45 = 12 So the differences are: 3, 6, 12, … Step 2: Observe the pattern in differences 3 × 2 = 6 6 × 2 = 12 Pattern: The difference doubles each time. Next difference = 12 × 2 = 24 Step 3: Find the next number Last number = 45 Subtract next difference: 45 − 24 = 21
