2,333 PointsRepeatDetector.Scan doesn't detect repetitions.
What am I missing here? Nothing looks wrong here to me. Unless TTH wants a specific implementation?
namespace Treehouse.CodeChallenges
{
class SequenceDetector
{
public virtual bool Scan(int[] sequence)
{
return true;
}
}
}
namespace Treehouse.CodeChallenges
{
class RepeatDetector : SequenceDetector
{
public override bool Scan(int[] sequence)
{
for(int i = 1; i < sequence.Length; i++)
{
if(sequence[i] == sequence[i]-1)
{
return true;
}
}
return false;
}
}
}

231,072 PointsYou're really close! But instead of decrementing the value of the indexed item, decrement the index instead so you can compare with the previous item:
// if(sequence[i] == sequence[i]-1) // original
if (sequence[i] == sequence[i-1]) // fixed
