Moo Of Doom

Good job, Bicycle Tree! You're good.

James R

Is anybody going to explain?

BicycleTree

Ok. The sequence is a palindrome.

Jimmy Snyder

In that case, 3 would serve as well (until moo added the extra condition).

ArielGenesis

what palindrome suppose to mean ?

Rahmuss

Man... darn... I saw it right after I looked at BicycleTree's response... Oh well.

Palindrome is the same backwards as it is forwards... they just have the commas in strange places.

NateTG

But there's an infinite number of options that makes it a palindrome. For example:
42861524251682435
142861524251682435
1142861524251682435
11142861524251682435
111142861524251682435
1111142861524251682435

And so on.

If you take the 4 (from the 24) as the middle of the sequence, then the numbers before and after are the same. So directly before/after the 4 there is a 2 then a 5 then a 1 then a 6 and then an 8 and so on. I would have thought that the answer could have also been:
'3, 5' (but then there would be more commas on the right of the 4)

PS

ArielGenesis

so the trick is just right at the comma. i got it. thx all
