I don't understand what this is asking me to do?

I need help on understanding the question I don't know what to do?

SequenceDetector.cs 
namespace Treehouse.CodeChallenges
{
    class SequenceDetector
    {

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

        public  override bool Scan(int[] sequence)
        {
            return true;
        }

    }
}

It looks like you're on task 3, which says, "Override the Scan method to return true if any value in the array is a repeat of the value immediately preceding it."

You've already done the override, so now you would add code to check if the condition is met. You will probably want a loop that goes through the items in the array and compares each one to the one next to it. If they match, you can can return true. Otherwise, after the loop finishes you can return false.

Hint you need 1 loop and one if statment they want to now if there are repetitions.
