    301, 300, 297, 292, 285, ?

    A.

    275

    B.

    276

    C.

    273

    D.

    277

    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)
