1, 2, 4, 6, 24, 100 HELP! What is the next number and how did you come up with this?
Here's ONE possibility:
1, 2, 4, 6, 24... 100, 200, 400, 600, 2400...
Magus is referring to a proof which shows that you can choose any number for the next in the series and then go back and find an equation to match.
He did not complete his work, however and show you the equation.
I would suggest that you post your question in the riddles forum.
The gentleman who claims kinship with the mythical figure is critical, perhaps even snide (?).
He provided no solution of his own, nor any explanation... merely demanding an answer that conformed to HIS requirements... and then told you where to go.
To accommodate the pragmatic one, I offer:
"a, a+1, a+3, a+5, a+23, a x 100, (a+1) X 100, (a+3) X 100, (a+5) X 100, (a+23) X 100... "
(I shall refrain from informing the "Godson" of the mythical druid where HE can go... )
Magus is illustrating the point that there are infinite solutions to your series unless you give more information.
However, I think that we can naturally assume some extra information...such as that if someone gives us a series and asks us to find the solution, that if the series is periodic, than at least 2 complete periods will be expressed in the numbers we know.
That said, I have spent too much time attempting to solve this series...whatever it is, it's no simple exponential. I wouldn't be surprised if there was rounding involved.
Has anyone considered that ccopley may be pulling our leg?
Why would the guy try to trick us on his first post?
Oh, and here's another ridiculously hard to solve series that has an equation
0, 1, 2, 3, 64, 390625

I hope I shall never hear another refrain this sour.
