875, 974

Rule: +99

[IceyLava108]

875, 974

Rule: +99

Dammit, I didn't think of that -- can you think of the one I thought of for this sequence?

[geodave]

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?

[geodave]

Sure looks like the prime number sequence....

How about

0,2,2,4,6,10,16,26,42,68,110....

[BlazingApollo]

That's fibonacci sequence results times 2, right?



My turn: 3,4,6,8,12,14,18,20,24,30

What's the rule?

[KeyboardWielder]

3,4,6,8,12,14,18,20,24,30

What's the rule?

Yeah, yeah... prime numbers + 1

Now sample this:-

10, 10, 10, 15, 10, 10, 15, 10, 40, __

[geodave]

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.
