Not original, though.

Actually, nobody would pick nine, because they would immediately realize they were falling into a trap of some kind.

My point was that "what's the next number" puzzles are never very good. It's always possible to run a polynomial through any N points on an xy-plane, and thus to come up with any answer you want.

I picked 9 because I thought it was a joke like my sequence.

In fact, if you'd read the thread, nobody would not pick nine

Yes, and that's why I picked 9 for the same reason.

So could you run one of those polly-normal jobbies and come up with the answer"9"?

I don't quite understand...

Code: Select all
y=2x-1+(x-1)(x-2)(x-3)(x-4)(x-5)(x-6)(x-7)...(x-anything)
is one example.
Another example is y=2x-1.

y=2x-1

So if y = 9 then x = 5
or if x = 9 then y = 17

So what?

What an odd way to look at this problem, no wonder all of you got fooled by Bill! One glance at the sequence should reveal the obvious answer:

y = 8½-|2(x-4¾)|
:D:D:D

Challenge: Create a polynomial that continues Bill's sequence to X=6 (Y=9).
