    A 432: 324 Correct Answer Incorrect Answer
    B 424: 318 Correct Answer Incorrect Answer
    C 572: 429 Correct Answer Incorrect Answer
    D 348: 257 Correct Answer Incorrect Answer

    Solution

    The pattern followed here is: The 1/4 th of the 1st number is subtracted from the 1st number to get the 2nd number. 432: 324 → 432 - 432/4 = 324 424: 318 → 424 - 424/4 = 318 572: 429 → 572 - 572/4 = 429 348: 257 → 348 - 348/4 = 261 ≠ 257
