Table of n, a(n) for n=1..16.
Index to sequences with linear recurrences with constant coefficients, signature (1,1154,-1154,-1,1).
|
|
|
FORMULA
|
On the odd and even indices respectively the same recurrence is obtained :a(n+2)=1154*a(n+1)-a(n)-192. we have also : a(n+2)=577*a(n+1)-96+68*(72*a(n)^2-24*a(n)-32)^0.5
G.f. -x*(1+35*x-437*x^2+205*x^3+4*x^4) / ( (x-1)*(x^2-34*x+1)*(x^2+34*x+1) ). - R. J. Mathar, Nov 27 2011
