FORMULA

a(n+2)=456302*a(n+1)-a(n)

a(n)=1501*{[228151+14820*sqrt(237)]^n+[228151-14820*sqrt(237)]^n}-(195/2)*sqrt(237)*{[228151-14820*sqrt(237)]^n}-[228151+14820*sqrt(237)]^n }, with n>=0 [From Paolo P. Lava (paoloplava(AT)gmail.com), Nov 25 2008]

EXAMPLE

a(1)=3002 because the first relation is 3002^2=237*195^2+79
