welcome! im the one in second place, namey
i think its sometimes quite challengeing, and you can learn lots of stuff from it!

## #2 Re: Help Me ! » sequence » 2005-08-07 14:36:01

it lasts until december, and starts again next year too!

## #3 Re: Help Me ! » sequence » 2005-08-07 10:43:37

so true. their answer depends on the ways you solve, how you look at the problem, etc. this one was a little ... over the edge. who would have thought of a sequence consisting add, subtract, multiply, and division of prime numbers?

yup

## #6 Re: Help Me ! » sequence » 2005-08-06 04:28:21

im trying to solve it before that
do you have msn IM?
we could discuss

## #7 Re: Help Me ! » sequence » 2005-08-06 04:27:16

yes, they post it tomorrow

## #8 Re: Help Me ! » sequence » 2005-08-06 01:52:08

i know what you mean

## #9 Re: Help Me ! » sequence » 2005-08-06 01:39:10

not really usually senior question are easier this one just ... dunno lack information or something. for instance, the code you found yesterday is perfectly reasonable

## #10 Re: Help Me ! » sequence » 2005-08-06 01:26:43

yeah, and it doesnt work

## #11 Re: Help Me ! » sequence » 2005-08-06 01:18:36

yeah thats waht i think

## #12 Re: Help Me ! » sequence » 2005-08-05 14:05:22

very reasonable if you ask me but apparently not

## #13 Re: Help Me ! » sequence » 2005-08-05 13:39:43

i dont know it was just for fun sortof
i was looking at the numbers and was adding stuff and found it. i didnt expect it to work

## #14 Re: Help Me ! » sequence » 2005-08-05 13:31:27

I Mean 16,15 Sorry

## #15 Re: Help Me ! » sequence » 2005-08-05 13:25:16

i'm not sure if its a coincidence, but look what i just found:
the last 2 numbers of sequence is "1156, 1125" add their first 2 values, or ones, gives us 256 and 225, which turns out to be both perfect square, and in order: they are 14,15 (14^2, 15^2)

oh ok

but you need a user id and pass word you can use mine

## #18 Re: Help Me ! » sequence » 2005-08-05 13:11:45

hmm... nice wcy. i m pretty sure that the pattern you found is no coincidence. im now looking deeper through the hints you gave me. there must be more factors to determine the next number....

## #19 Re: Help Me ! » sequence » 2005-08-04 12:06:44

i kind of thought about that, but the first two lists they just increase all the way, and the last one decrease to 1125 from 1156. another mystery.

## #20 Re: Help Me ! » sequence » 2005-08-04 11:11:08

i see what you mean. still having some ideas are better then nothing right?

## #21 Re: Help Me ! » sequence » 2005-08-04 06:31:13

it's from a contest  online. what i posted previously was all that was to the question. the sequence looks kind of odd, so i reckon there is a "semi-mathematical" sequence behind it. do you have any suggestions what the next number can be, just any random suggestion?
