**Reiny**, Sunday, October 4, 2009 at 6:58pmthe sequence runs this way :

1 2 3 2 1 1 2 3 ..

it repeats!

the first loop is 1 2 3 2 1

the sum of that loop is 9

so as long as we add up to the end of a loop we have multiples of 9

If we add up 223 loops the sum is 2007

adding the next digit, which is a 1 would give up 2008, and if we add the next one after that, we would get 2010

So it is not possible for a sum of 2009, but we will reach 2010
