Correct option is B
Given:
Series: 301, 300, 297, 292, 285, ?
Logic: numbers are decreasing by odd numbers starting by 1. Pattern of differences: −1, −3, −5, −7
Facts & Explanation (Operation-wise):
301 → 300 = −1
300 → 297 = −3
297 → 292 = −5
292 → 285 = −7
=> Next difference = −9
Now,
285 − 9 = 276
Final Answer: 276
Final Correct Option: (b)
