      Find the wrong number in the given number series.

      5, 30, 255, 860, 2105, 4130
      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.
