These are the difference of the numbers in above series.
So, the first one should be 30.
And how did you get 2742?


516,1002

so now,

1740+991=2731

so

2731+2742=5473

No idea. I couldn't find the sequence in the OP at
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.
