Programs to find number patterns

  1. Aug 7, 2004 #1
    Are there any programs that can be used to find out what numbers have in common?

    eg,

    748805534073
    408986296450
    445580425891
    399528663101
    571646773773

    can't find anything to do it :confused:

    cheers

    There's too little info in this query. What are you looking for ? And why ? Some context may help...

    Here is always a good place for sequences: http://www.research.att.com/~njas/sequences/

    However it does not seem to find your numbers in any sequence. I once wrote a number program that gave many properties of a number however I think your numbers are too big at the moment (I'm writing a newer version) sorry :frown:

    The first thing you are going to have to do is describe exactly (mathematically) what you mean by "have in common"!

    They're obviously the first 5 terms in the sequence a_n = (63322918749/2)n^4 - (2358746821765/6)n^3 + (3510834041869/2)n^2 - (19974725393909/6)n + 2683972423043.

    If you have X numbers, you need a maximum of a (x-1)th degree polynomial to put them all in a function. 1 point requires a 0th degree (y=6), 2 requires a line (y=2x+6), etc. With 5 numbers it may take awhile to solve, though.
