Correct Answer: 60
Solution : Given: (2, 8, 20), (7, 12, 22), (33, 42, ?)
Like, (2, 8, 20)→8 + ((8 – 2) × 2) = 8 + (6 × 2) = 8 + 12 = 20 (7, 12, 22)→12 + ((12 – 7) × 2) = 12 + (5 × 2) = 12 + 10 = 22 Similarly, follow the same pattern for (33, 42, ?)→42 + ((42 – 33) × 2) = 42 + (9 × 2) = 42 + 18 = 60
So, 60 is the required missing number. Hence, the fourth option is correct.
