5473

1,31,253,991,2731

1,222,738,1740,2742

516,1002

so now,

1740+991=2731

so

2731+2742=5473

1,222,738,1740,2742

516,1002

so now,

1740+991=2731

so

2731+2742=5473

i didn't get it....

1,222,738,1740,2742

So, the first one should be 30.

And how did you get 2742?

516,1002

so now,

1740+991=2731

so

2731+2742=5473

yes nimes, the first number should be 30, dat was my mistake.

2742 i got like dis....

1740+1002=2742

2742 i got like dis....

1740+1002=2742

6121

But what is so special about the other series

http://www.research.att.com/~njas/sequences

but swapping the commas for spaces they all showed up in only one sequence http://www.research.att.com/~njas/se...lish&go=Search

and there were 2,5,8,11 numbers between them. 2,5,8,11 shows up in 65 sequences and has varying numbers after it, but 14 seems common. So this leads to my guess of 6121.

Lets see if after 24 hours what the OP replies to
