    A 43 Correct Answer Incorrect Answer
    B 49 Correct Answer Incorrect Answer
    C 59 Correct Answer Incorrect Answer
    D 71 Correct Answer Incorrect Answer

    Solution

    For the first: 3 × 1 × 5 × 2 = 30, which is close to 31 (off by 1) For the second: 4 × 6 × 3 × 2 = 144, which is close to 145 (off by 1) So the missing center value would be: 2 × 7 × 5 × 1 + 1 = 70 + 1 = 71
