    A 860 Correct Answer Incorrect Answer
    B 2105 Correct Answer Incorrect Answer
    C 255 Correct Answer Incorrect Answer
    D 4130 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    5 + 5² = 30

    30 + 15² = 255

    255 + 25² = 880

    880 + 35² = 2105

    2105 + 45² = 4130

    Therefore, 880 should come in place of 860. So, 860 is the odd one out.
