Dammit, I didn't think of that -- can you think of the one I thought of for this sequence?
/confusing
Sequences - geodave - 31-May-2012
667, 776, ____
As stated previous, there are lots of options, ESPECIALLY when you only have two numbers to start with -- it could be almost anything. +99 was just the simplest (from my pov). Anyway, I think I made an error, as 776 - 667 = 109
So, what I should have said was: 667, 776, 885, 994....
And then there's 667, 776, 667, 776 .... (the rule seems obvious)
More fun is 667, 776, 677, 766, 777 .... which is derived from successive pieces of this sequence: 667776677766777
Or, in a really odd way, it could be 667, 776, 946... which would translate on a phone dial pad to "mop pro win"
It's probably something else, though.

No, you got it Dave --- the repeat of 667 and 776
Here's a long one to make sure there's only ONE rule that can be made here!
2,3,5,7,11,13,17,19,23,29,31,37,41,43,47,53,59,61,67,71,73,79,83,97,101,103,107,109,113,127,131,137,139,149,151,157,163,167,173, _

Prime numbers?
Sequences - geodave - 01-Jun-2012
Sure looks like the prime number sequence....
How about
0,2,2,4,6,10,16,26,42,68,110....

That's fibonacci sequence results times 2, right?

My turn: 3,4,6,8,12,14,18,20,24,30
What's the rule?

What's the rule?
Now sample this:-
10, 10, 10, 15, 10, 10, 15, 10, 40, __

Sequences - geodave - 01-Jun-2012
Actually, mine was an alternate fibonnaci sequence starting with 0 and 2, but it amounts to the same thing.
10, 10, 10, 15, 10, 10, 15, 10, 40, __
That's tricky. Looks sort of like a tennis score.
Let's try the difference method
0,0,5,-5,0,5,-5,30
0,5,-10,5,5,-10,35
5,-15,15,0,-15,45
-20,30,-15,15,60
50,-45,30,45
-95,75,15
180,-60
-240
-240,-240
180,-60,-300
-95,75,15, -285
50,-45,30,45,-240
-20,30,-15,15,60,-180
5,-15,15,0,-15,45,-135
0,5,-10,5,5,-10,35,-100
0,0,5,-5,0,5,-5,30,-70
which would make the next number -30. I'm guess that's NOT what you were looking for.
