    C 350 Correct Answer Incorrect Answer
    D 145 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    350 – 61 = 289

    289 – 51 = 238

    238 – 41 = 197

    197 – 31 = 166

    166 – 21 = 145

    Therefore, 166 should replace 158.
