The nth term of the sequence is equal to b(n), where b(n) denotes a blahpy number. The 10th term of the sequence is 335833314.

The first few blahpy numbers are defined as:

b(1) = 320057779
b(2) = 45232
b(3) = 10004921
b(4) = 81263099
b(5) = 190134
b(6) = 319944613
b(7) = 55815655
b(8) = 326755503
b(9) = 56536998
b(10) = 335833314

It seems that when x=y=z=1/2k, it is the maximum of xyz, but I can't explain in detail to make a proof orz
lgdry15
设x+a=y+b=z+c=k,则xyz=abc
所以,根据均值定理,
k>=2*sqrt(xa)
k>=2*sqrt(yb)
k>=2*sqrt(zc)

所以k^3>=8*sqrt(xyzabc)
又xyz=abc
所以k^3>=8*(xyz)
所以xyz<=(k^3)/8

得证! :)

https://osu.ppy.sh/s/178495 :)
lightr
令Z≥X≥Y,所以XYZ的最大值为Z^3且等于(K-Z)的三次方

---> Z^3 = (K-Z)^3
---> Z=K-Z
---> Z=1/2K

所以Z^3=(1/2K)^3 , 这个是最大值

所以XYZ小于等于K^3/8

if x=4, y=6 z=5 and k = 10, then?
if x, y, z < k/2, substitute them into xyz to get xyz < k^3 / 8

if x, y, z > k/2, then k-x < k/2, k-y < k/2, k-z < k/2
then xyz = (k-x)(k-y)(k-z) < k^3 / 8

for effort...please?
wmfchris
As lgdry15 got the correct answer I will perform a standard trick towards the solution.

Let u = (k-x)/x, v = (k-y)/y, w = (k-z)/z (The case for x/y/z = 0 is obvious, so WLOG suppose they are positive.)
Then x = k/(u+1), y = k/(v+1), z = k/(w+1)

So that the equality becomes uvw = 1 and to show that (u+1)(v+1)(w+1) >= 8k^3.

Since u,v,w > 0, the result is obvious by AM-GM.
