Lie Detection

[halex44]

1. Statement number 3 is a lie.
2.statement number 4 is false.
3. The statement above this one is a lie.
4. The statement below is true.
5. Statement number 2 is false.

if 1 is a lie, 3 isn't a lie, which makes 2 a lie.
if 2 is a lie, it makes 4 false, which makes it a lie.
if 3 is a lie, makes 2 true, which makes 4 false which makes 5 a lie.
if 4 is a lie, 5 is false, which means 4 can't be true -> because it's a lie, it makes it 4.
if 5 is a lie, 4 has to be a lie too.

It is 4.

"1. Statement number 3 is a lie.
2.statement number 4 is false.
3. The statement above this one is a lie.
4. The statement below is true.
5. Statement number 2 is false."

There is not just one lie present.

There is no distinction between a lie and a false statement. Halex is posing each statement, knowing the supposed answer. If he puts a statement that is knowably false, he is by definition lying. Thus lies and false statement are treated the same.

Suppose four statements are true. Of the five presented, four claim that others are a lie. Of those four, the ones claimed to be lies are statements 3, 4, 2, and 2. This means that if exactly one of those statements was a lie, there are two others still claimed to be lies, unless the only opposing claim is made by the lie itself. Since statements 3 and 5 say the exact same thing, they must both be true (as they cannot both be lies). They say that statement 2 is a lie. Statement 2 claims that statement 4 is false, but since this is a lie, then statement 4 must be true. Statement 4 claims that statement 5 is true, which we already know since it matches statement 3. However, statement 1 must be true (since statement 2 is the lie) and thus it states that statement 3 is actually a lie, which cannot be the case. This means that there are no solutions with exactly one lie, which breaks the rules of this game.

With that being said, the following truth-lie correlation would work with the least number of lies:
1 is a lie
2 is a lie
3 is true
4 is true
5 is true

The other solution is this:
1 is true
2 is true
3 is a lie
4 is a lie
5 is a lie

I concur with yeroc's logic. Therefore, as the thread originator, I am going to say that halex has forfeited his turn and yeroc is up .

 

[halex44]

It made sense in my head lol

I think if either 7 or 6 is true the other one is true too so i am gna say 10.

 

[Srentiln]

I'm fairly certain I know which is the lie, but by my own rules I can't guess yet

 

[yeroc424]

My name is not Cornelius, unfortunately. I wish it was. Sren, what was your guess?

Piece is up.
