Repeatdetector detects repititions when there are none

I dont have a clue? Can anyone help me.

SequenceDetector.cs
namespace Treehouse.CodeChallenges
{
    class SequenceDetector
    {
        public virtual bool Scan(int[] sequence)
        {
            return true;
        }
    }

  class RepeatDetector : SequenceDetector
    {
        public override bool Scan(int[] sequence)
        {
            return true;
        }

Right now your method always returns true.

But the instructions say that it should "return true if any value in the array is a repeat of the value immediately preceding it". So you probably want a loop that steps through the array, starting with the second item, and compares each item to the one before it. If there's a match, return true. If the loop finishes without finding a match, return false.

Also, while it doesn't seem to affect the challenge, I think the work for tasks 2 and 3 was intended to be done in the other file (RepeatDetector.cs).
