1. ## Number Sequences

Can you solve these problems?

2. Solutions I got so far:

Sequence 1:

Sequence 2:

sequence 3 (debatable solution):

3. Can I ask how strict the third is in terms of reaching an answer? I can imagine there is probably an actually mathematical formula with a repeater that can explain that sequence, but since ms calculator sucks and I dont take the time to write stuff down on paper, I can't be bothered trying to find that formula.

I do see a pattern in it though, which would result in the answer being 4/7. But it's not too obvious.

7/7 = 1
6/6 = 1
5/8 = .625
4/7
3/9 = 1/3

76543=-1 repeated and 76879 = 7-1 = 6+2 = 8-1 = 7+2 = 8 = (-1 -> +2) repeated

The other four sequences seem rather random to me. Probably need some kind of context for them to make sense, just like the second one that is just simple hexadecimal code sequence of 1, 10, 100, 1000. But without knowing about hexadecimal code you won't get it.

The first one with the 013 for example, definately means it's not just a mathematical formula. Otherwise it would just say 13. But what is the context of the sequence amd the meaning of the zero before the thirteen? That must be the riddle. I'll ponder on it some, maybe I'll get it. Hah, I got it!

4. Sorry...why the second answer is 64 ?
The third answer must be truth.

Easy one!

I'm still working on the other ones.

decimal - 0123456789

1= 1
A= 10
64= 6 x16 + 4=100
3E8= (3x16 + 14)x16 + 8=1000

1, A, 64, 3E8 = 1, 10, 100, 1000

6. I've got it!!!
You're genius

1, A, 64, 3E8 = 1, 10, 100, 1000

7. Like that was ever in doubt.

In all fairness though, I've worked with hexadecimal code a lot, so I spotted it rather quickly. Instantly. >.>

edit:

I've not gotten very far with the other four though. Although I can't say I've really tried either. From first observations, none of them seem to have a logical mathematical equasion assigned to them, or perhaps do but are then encoded in one way or another. There are just so many ways of encoding something that it could take a long while to figure these all out.

Now if figuring these out would cure cancer, I'd be all for that. But just so I can say I cracked it is not going to be good enough for me to spend large amounts of time on these. :P

I'll look at them now and then when I have some time and am on the forum. But I don't think I will be the one to crack the other four. xP

78, ?, 81, 48, 304, 503, 307, 013, ?, 1128

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. >.<
