Terms of the simple continued fraction of (131+5*sqrt(1429))/182. Decimal expansion of 3791/33333. - Paolo P. Lava, Aug 05 2009

LINKS

Table of n, a(n) for n=0..104.

Index entries for linear recurrences with constant coefficients, signature (0,0,0,0,1).

FORMULA

a(n) = (1/10)*(7*(n mod 5)+11*((n+1) mod 5)-5*((n+2) mod 5)-((n+3) mod 5)+3*((n+4) mod 5)). - Paolo P. Lava, Nov 19 2007

a(n) = n^2 - n + 1 (mod 10). - Arkadiusz Wesolowski, Jul 02 2012

G.f.: (1 + x + 3*x^2 + 7*x^3 + 3*x^4)/(1 - x^5). - Arkadiusz Wesolowski, Jul 03 2012
