The first two numbers of the fourth sequence have an obvious pattern in them (12345 -> 21354), but there are not enough numbers in the sequence to justify the three after that by the same patterns. I doubt they meant for the ? to be 82605 as the fifth number serves no puropose then. But then again, 12345 cant be a coincidence? Anyway, I'm not seeing the logic of the entire sequence. >.<
I saw the same thing in the fourth sequence, but I can't work it out, either.

Yeah, under the assumption that all given numbers are of significance, the fifth number's sudden jump to in the millions seems inexplicable, if you would try to assign any mathematical formula to it.

So it must have a more elusive reason for its numbers, quite possibly to do with the triple 1's, the 83 and 84 as well as the obvious 12345 in the first number and the fact the second also consists out of the numbers 12345.

3. Just curious, but is anyone else also trying to solve these? Or am I the only one bothered enough to give it some thought? xP

Maybe, these problems are too difficult for others to solve them.

I got nostalgic and just checked out these number sequences. Although the other three are still lost on me, I somehow failed to see that the one above is also the sum off the previous four encoded numbers which means that there's another inverse I missed.

Like so:

78 -> 79 -> 81 -> 84 = 78, 97(inv), 81, 48(inv)
78+97+81+48=304
304-> 305 -> 307 -> 310 = 304, 503(inv), 307, 013(inv)
304+503+307+013=1127(inv) <- that's the one I missed that explains the two jumps and makes the sequence limitless. (although there is no four numbers prior to the sequence that sums up to 87, so 78 is truly the start of the sequence.)
1127->1128(->1130->1133) = 7211(inv), 1128 (,0311(inv), 1133)

so although my previous answer seemed correct, it actually wasn't and the praise was unfortunately misplaced.

78, 97, 81, 48, 304, 503, 307, 013, 7211, 1128, (0311, 1133)

Weird that I didn't see this when I was working on this before. But I saw it fairly quickly just now. :P

Yeah this thread is making me less intelligent by the second. Mathematical intelligence is so much more impressive than any other.

No amount of extra help could ever save me though!
