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

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/ [Broken]

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

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.
