 OFFSET 1,1 COMMENTS Sequence is periodic with period 2. - Charles R Greathouse IV, Jul 27 2009 LINKS A. Frank & P. Jacqueroux, International Contest, 2001. Item 29 Index entries for linear recurrences with constant coefficients, signature (0, 1). FORMULA a(n)=388578+125064*(-1)^n, with n>=1. - Paolo P. Lava, Aug 04 2009 EXAMPLE Since a(1)=263514, the '2'nd digit of a(2) is 1, the '6'th digit is 2, the '3'rd digit is 3, the '5'th digit 4, the '1'st digit is 5 and the '4'th digit is 6.
