The n+1 terminal digit, where the Fibonacci number ends in 999 {n=3}, has a cyclic period of 10 with the tenth occurance being a 9, itself. I.e., 1497+15000(x1), where x is the xth occurance of the Fibonacci number ending in 999.. The n+1 terminal digit, where the Fibonacci number ends in 9999 {n=4}, has a cyclic period of 10, with the tenth occurance being a 9. I.e., 1497+150000*(x1). For n=3, the n+1 terminal digit is equal to [7*(x1)+6] modulo 10.
