Sequences

Recommended Posts

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.

Didn't we just do fibonacci?

 

I cannot spell fibbonaci.

 

you'll never get this one (unless you google it):

 

3,7,15,1,292,1,1,1,2,1,3......

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

 

That's tricky. Looks sort of like a tennis score.

 

Here are the next few numbers in the sequence:-

... 8, 30, 40, 0, 25, 25, 0, 10, __

 

By 0 actually I mean infinity (or to be more precise, 10% of infinity).

The sequence itself is finite, though.

10% of infinity? It's been a long time since Number Theory class, but doesn't 10% of infinity = infinity?

 

I still have no idea. Any ideas on mine?

 

Let's try this one:

 

0,2,16,54,128,250,432,686,1024,....

(x^3)*2

 

Woah, did I actually figure one of these out? :blink:

 

Yes you did!

 

Let's have a little more fun.....

 

70,60,45,25,0...

I took your word for it and didn't even try. :P The 292 just looks evil.

 

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

... 8, 30, 40, 0, 25, 25, 0, 10, __

It's been a long time since Number Theory class...

If you've learnt your Lessons well, the first eight should be a cakewalk. ;)

I'm still lost.

 

The 292 is pretty wild. The sequence is the continued fraction expansion of pi (I guess pieguy didn't see it.)

What I posted in the "The person below me" thread:

False. I don't have any.

 

The person below me knows what should replace the question mark in "fadhatpbmkwsrt?mi"

 

EDIT: fidhatpbmkwsrt?mi
