    {
        public override bool Scan(int[] sequence)
        {
            for (int x = 1; x <= sequence.Length; x++)
            {
                if (sequence[x]==sequence[x-1])
                {

Try this

namespace Treehouse.CodeChallenges
{
    class RepeatDetector : SequenceDetector
    {
        public override bool Scan(int[] sequence)
        {
            for (int x = 1,y=0; x < sequence.Length; x++,y++)
            {
                if(sequence.Length == 1)
                      return false;
               else
                  {
                      if (sequence[y]==sequence[x])
                         {
                       return true;
                          }
                  return false;
                 }
            return false;
            }
        }
    }
}
