I did not really understand what to do in this

Subclass the SequenceDetector class call the new class RepeatDetector. Can you help me out here?

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

If you don't know how to even begin a challenge, it might be a good time to review a lesson or two.

The process of subclassing is presented in the Virtual Methods video. Your task here of using "SequenceDetector" to create "RepeatDetector" is very similar to the where the video uses "Invader" to create "ShieldedInvader".
