• A. 22
• B. 52
• C. 116
• D. 244

Answer 1

Answer:

D. 244

The wrongly placed number in the series is 244.

To find the pattern, let's examine the mathematical relationship between each consecutive number in the sequence:

• $9 \times 2 + 4 = 18 + 4 = \mathbf{22}$

• $22 \times 2 + 8 = 44 + 8 = \mathbf{52}$

• $52 \times 2 + 12 = 104 + 12 = \mathbf{116}$

• $116 \times 2 + 16 = 232 + 16 = \mathbf{248}$
