another pretentious number sequence

Postby a1s » Fri Sep 25, 2009 1:05 am UTC

here is a number sequence:
2334, 741, 1943, 390, ...?
try to figure out the next number, or make a lucky guess :wink: .

hint 1:
Spoiler:
I guess the sequence could have had 333, 1134 in the beginning (so it would be 333, 1134, 2334, 741, 1943, 390...) but there are aesthetic reasons to start with 2334.


hint 2:
Spoiler:
I guess none of you were taught New Math, or this would have been solved by now...

while we're waiting, have you ever considered what life is like for children who are missing 3 fingers? They must have problems picking stuff up, and with math...

Are you sure that's 1943 and not 1934?

I've never understood the point of these, as there are an infinite number of possible sequences that fit the known data, and there will as long as you give us a finite number of terms. How do we know which one you're looking for?

The one he thinks is right is the right one; hence, "Pretentious Number Sequence"

chridd is correct.
as is MSTK abou the principle for determining the right answer.
For additional points, find as many rules as you can (I'm not saying there's more than 1- I haven't checked) that do not include septic (7th degree or above) polinomials. :wink:

Rule 1:
Sequence is 333, 1134, 2334, 741, 1943, 390, followed by 0's

Rule 2:
Sequence is 333, 1134, 2334, 741, 1943, 390, followed by 1's

etc

No more arbitrary than saying it's the values of a polynomial with equally arbitrary coefficients

let me clarufy the chalange: the sequence is 333, 1134, 2334, 741, 1943, 390, 1534, 333, 1134... and so on cyclically. The puzzle is to find some kind of rule that would describe such a sequence.

(I you might object to the use of this particular sequence, rather than 333, 1134, 2334, 741, 1943, 390,1,1,[1], but since chridd found it on his first guess, and goplat actually corrected a typo in the sequence, there must* be something special to it)

*)or, to be more precise, there's a very high probability that is true.
