Those are particularly horrible…

Another wacky number game from the same guy:

I love Numberphile. They are on Patreon now…

For all the people complaining that these aren’t “proper” mathematical sequences, this is Niel Sloane, creator of the On-Line Encyclopedia of Integer Sequences, having a little fun.

Yawn… the solutions are not unique. For any given sequence a,b,c… create the polynomial (x-a)(x-b)(x-c)*[anything you want] = 0 and you have a valid solution for subsequent terms. Maybe not the one the puzzler wanted, but that just means the puzzlemaker doesn’t know algebra

Let’s see, to reduce 16/64 just cancel the sixes above and below the line leaving 1/4. It works! And is equally silly and useless.

I dont enclose my fours so I had no hope of solving.

I had to stop, my brain started hurting.

I got the ONE = 0, TWO = 0, […] FIVE = 4 sequence immediately. It was the only one. I had a decent guess with the EBAN numbers, right direction but wrong solution.

God, the sound of that marker on that paper – eeeeew.

googol plex!

When I am having trouble falling asleep I do the math of The Fibonacci Sequence : **1** , **1** , **2** , **3** , **5** , **8** , 13, 21, 34, 55, 89, 144, 233, 377, 610

Or 1+1= 2, 1+2= 3, 2+3= 5, 3+5= 8, … etc

Zzzzz…

There’s a unique blend of frustration/annoyance I get when approaching a problem in good faith, only to be repeatedly told how *simple* it all is while someone explains the gimmick through a shit-eating grin. Tackling problems is fun and rewarding even when you fail (which I usually do) but these seem like they aren’t solvable without disingenuous bait-and-switch criteria. Handwriting? The spelling of the numerals, but only in English? Come on now…

Indeed, these felt more like linguistic or typography puzzles than math problems…

(and yes, as a non-english speaker, I automaticaly revert to my native language when doing math puzzles and these become unsolvable…)

What if i write my 6 like this? And my 9 the opposite of that? Then what???

OMFSM, it doesn’t work! Oh, nooooes!!!

Oh, that’s just the point when you just move all the commas in the sequence to the left. No problem.

… and omit zeroes because they foul up the other (more logical) solution…

I pick an arbitrarily large number and count down by sevens.

I got another of those sneaky questions. See if he can solve this.

What’s the next number in the sequence?

134, 24, 34, 44, 54, 634, 754, …

ps, it’s easy! (if you know the rule )

Cool! Also I do the Alphabet backwards. Zzzzz…

But are any of them numberwang??

Neil has some pretty insane wallpaper in his office.
