What is the next number in this sequence and why?

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.

I must say it saddens me when I see two members of high intellect and renown engaged in a misunderstanding. Whilst, alas it is all too familiar in some of the ?'blood sports' forums, surely Science and Math should lead the way in setting the highest standards of decorum.

Magus writes, "…"Godson" of the mythical druid…)

This is quite amusing when one considers:

Magus is one of the primary sources for the study of ceremonial magic, and for a long time was one of the rarest and most sought after of the 19th century grimoires. Barretts' magnum opus embodies deep knowledge of Alchemy, Astrology, and the Kabbalah, and has been cited by the Golden Dawn and other occult and esoteric movements as source material.
Written in 1801 in the middle of the 'Age of Reason', sandwiched between Newton and Darwin, this was possibly the last epoch that a work like this could be composed.

That said, I thank you for using the word ?'pragmatic'. I have not seen that in print for many a long year. A wizard like repartee.

Riddles rule KO! (Sorry, I am a bit dyslectic twoday)
