    C 235 Correct Answer Incorrect Answer
    D 310 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ, 300 + 20 * 1 = 320 320 + 20 * 2 = 360 360 + 20 * 3 = 420 420 + 20 * 4 = 500 500 + 20 * 5 = 600 So the common pattern is adding 20 × 1, 20 × 2, 20 × 3, 20 × 4, 20 × 5. Thus the missing term is: 300 + 20 * 1 = 320 Hence 320 will come in place of (?)
