Vincenzo Librandi, Table of n, a(n) for n = 0..10000
Index entries for linear recurrences with constant coefficients, signature (5,-10,10,-5,1).
FORMULA
a(n) = 5*a(n-1) - 10*a(n-2) + 10*a(n-3) - 5*a(n-4) + a(n-5); a(0)=625, a(1)=28561, a(2)=194481, a(3)=707281, a(4)=1874161. - Harvey P. Dale, Dec 17 2013
G.f.: ( -625 - 25436*x - 57926*x^2 - 14236*x^3 - 81*x^4 ) / ( (x-1)^5 ). - R. J. Mathar, May 08 2015
