starting with 2,0,0,5 form the sequence 2,0,0,5,7,2,4,8,1 ...
where each successive digit is the unit digit of the sum of the previous 4 ( 2+0+0+5=7, 0+0+5+7=12 , write 2, .. etc.)
does the sequence 4,0,5,3 ever appear ? prove your answer
i have been trying to see some sort of pattern.. but i can't figure out anything
if anyone has any idea how to do it.. or maybe a hint.. i would really appreciate it..
thanks
