    C (82, 94, 36) Correct Answer Incorrect Answer
    D (50, 72, 60) Correct Answer Incorrect Answer

    Solution

    The middle number (Second) is the sum of the First number and one-third of the Third number. (42, 54, 36) → 42 + (36 ÷ 3) = 42 + 12 = 54   (75, 90, 45) → 75 + (45 ÷ 3) = 75 + 15 = 90 Checking the Options Option A (64, 80, 48) → 64 + (48 ÷ 3) = 64 + 16 = 80 Option B (28, 43, 45) → 28 + (45 ÷ 3) = 28 + 15 = 43 Option C (82, 94, 36) → 82 + (36 ÷ 3) = 82 + 12 = 94 Option D (50, 72, 60) → 50 + (60 ÷ 3) = 50 + 20 = 70 ≠ 72.
