    Find the wrong number in the given number series.

    3, 7, 22, 89, 445, 2675

    B 2675 Correct Answer Incorrect Answer

    D 7 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    3 × 2 + 1 = 7

    7 × 3 + 1 = 22

    22 × 4 + 1 = 89

    89 × 5 + 0 = 445

    445 × 6 + 0 = 2670
    Correct value should be 2670, not 2675
