Determine x in this loop:

9 – 80 – 63- 44 - x – 9 – 80 – 63 – 44 -……

Show your work.

I found x :) It is located between 44 and 9. Isn't "determine x" more accurate?

Edit: My guess would be 27.

Yes, but the loop is just repeated after 4 numbers :)

I believe you are right at least :P otherwise it wouldn't be a loop right?

Well, I guess it's possible, but it seems a bit forced. :s

You'll still get your gift if I don't have a satisfactory answer in ~30 mins :)

Of course I am right, I teach maths. If you don't like a problem, invent/define something that the problem is solved.

Be very careful with jokes like that. It might be considered begging and earn you a 4 days suspension. Check here.

ow, no, didn't mean it like begging, after all, I said to do it fairly, not just giving it to me.

best way would probably be a new giveaway, because technically, you already solved it, so it would just be a matter of copy pasting your answer, that would not be a fair gib right?

Supports don't care if you are joking or not. They suspend all begging or joking (about begging) alike.

As the comment is deleted and you are not suspended, it seems to be fine. We commented, because you are new to the site :)

You are lucky no mods are looking at this thread (or actually online at all). Last time I saw another user got suspended in 30 seconds right after I warned him. Just bad luck :P

My guess is x = 31.

Here's the assumed rule of the loop

(first digit) ^ 2 - 1 + (second digit; 0 for a single-digit number) ^ 2

We have:

80 = 9 ^ 2 - 1 + 0 ^ 2
63 = 8 ^ 2 - 1 + 0 ^ 2
44 = 6 ^ 2 - 1 + 3 ^ 2
31 = 4 ^ 2 - 1 + 4 ^ 2
9 = 3 ^ 2 - 1 + 1 ^ 2

Am I wrong to say that works but by doing that you're actually using the 9 as if it was 90? Still want you to get the game and hope you already have it but I like this puzzle, I'm interested to really know what x is :) Spot the nerd :)

If we represent all numbers with two digits (e.g., 09), we can slightly modify the rule to:

(greater digit) ^ 2 - 1 + (lower digit) ^ 2

(Here, greater and lower correspond to the actual value, not the index.)
