Let z(k) be defined as follows :
z(0)=4^n ; z(k)=4^(n-k)+sqrt(z(k-1))
Let S(n)=sum(k=0,n,1/z(k))
Let T(n)=sum(k=0,n,1/(2^k+1)^2)
I found experimentaly :
S(n)-T(n) = 2/8^n + 13/16^n + 132/32^n + 4283/64^n + 260102/128^n +
32852729 /256^n+ 8341600776 /512^n+O(1/1024^n)
How the sequence of numerators continues ? Is there any pattern?
