Guess the Rule ~ An Interactive Game!

Hey Guys!

This is an interactive "game" of sorts, where you are the participants.

To those of you who already know about this game, please don't spoil it for the rest by commenting on this post. You're welcome to join in on the discussion of the game after it's over. And now, let's begin!

The Rules of the Game

  1. I have a mathematical rule in mind, which applies to ordered triplets of non-zero real numbers. Some triplets of numbers fit that rule, other triplets of numbers do not.
  2. Your objective is to guess that rule correctly.
  3. To begin with, I will give you a single triplet of numbers that fits the rule.
  4. You are allowed to give me some triplets of numbers by posting each triplet as a separate comment, and I will tell you whether or not your triplet satisfies the rule by replying "Yes" or "No".
  5. Once you are certain what the rule is, post it as a reply to my comment "Please post your final answers here."

After the game ends (that is, when the first correct answer is posted), the discussion of this game and its implications will be posted as a new note, which I will link to here.

The first person to guess the rule correctly wins a solid-gold virtual trophy, followed by a tray of freshly-baked virtual cookies and a glass of virtual milk. But seriously, you might just learn something from this, so join in!

The first triplet which satisfies my rule is:

\[\Huge 6,8,10\]

Update 1

Well, many people have commented, some nearing very close to the answer. Remember, the rule may not be a simple rule. It can include several different aspects, and you have to discover all of them. For example, I've given you one part of it already, that only real numbers can be part of the triplet. I also told you that they have to be non-zero. So, with this information, your starting rule should be something like, "A triplet of non-zero real numbers."

There are other aspects to the rule, some of which you have guessed correctly. Two more aspects remain. Who will figure those final aspects out? And don't worry, though the rule is somewhat arbitrary, it's not as arbitrary as "The sum of the three numbers should not be 42." Cheers!

Update 2 The game is now officially over. Angela Fajardo won the competition!

the triplets should not be a negative number , should be increasing order and the numbers should not repeat

Angela Fajardo - 2 years, 10 months ago

Log in to reply

A triplet of non-zero real numbers should be in an increasing order , not have a negative number , and don't have a repeating number.

Angela Fajardo - 2 years, 10 months ago

Excellent, great job! You win! My phrasing was: three distinct, positive real numbers arranged in increasing order.

@Raj Magesh nope , the numbers should be increasing too.

@Angela Fajardo Great job, you're almost there. One more condition is left. Check the triplets you posted once more.

On this occasion of the new year I declare the all of your triplets follow Pythagoras theorem!

Sarthak Tanwani - 2 years, 10 months ago

Nope.(13,16,19),(1,2,3) also follow the rule but aren't Pythagorean triplets

Close. Two more aspects remain. Can you figure those out? How would you go about it?

For a triplet (a,b,c),a^2 plus b^2 equals c^2.Lengths of right triangle.

Abdur Rehman Zahid - 2 years, 10 months ago

Log in to reply

real numbers \(a, b, c\) such that \(a \le b \le c\) and \(a^2 + b^2 = c^2\). Note that a right triangle can't have negative length :)

Still nope. Did you check out all the triplets others posted?

Note that this game is very similar to Zendo in its core.

I wonder if a game of Zendo will attract people...

Okay, thank you. I'm probably know what the rule is, but just to make the game longer and for others to have fun, I'll probably just sit this one out until the game ends.

@Tytan Le Nguyen Great, but stay tuned, you might just be wrong! ;) Cheers!

@Raj Magesh Oh, one more question just to be sure. Would any of the triplets (8, 15, 17) and (20, 21, 29) fit this type of triplet?
