A120

B148

C361

D247

Answer:

A. 120

Read Explanation:

Find the pattern in differences:

  • 183 − 150 = 33

  • 219 − 183 = 36

  • 258 − 219 = 39

Differences increase by 3.

So the previous difference should be:

33 − 3 = 30

Therefore, missing number:

150 − 30 = 120

So, the answer is 120.
