B Correct answer
Explanation

The series follows a pattern of dividing by 2. 4480 / 2 = 2240 (not 2250), 2240 / 2 = 1120, 1120 / 2 = 560, 560 / 2 = 280, 280 / 2 = 140. Thus, 2250 is the wrong number.

AI explanation

The series follows a pattern where each term is half of the preceding term plus one. Applying this logic, 2250 should be 4480 / 2 + 1 = 2241, and 1120 should be 2250 / 2 + 1 = 1126. Therefore, the number 2250 is the wrong term in the sequence. The result is 2250.
