**drwls**, Sunday, June 21, 2009 at 6:03amThe positive integers +1, +3 and +5 are not of that form, unless q can also be zero.

The difference between 6q + 5 and 6q' +1, if q' = q+1 , is

[6(q+1) + 1]-[6q +5] = 2

That means that by increasing q by 1 when you get to 6q+5, the next number will be 2 greater, so that all odd numbers can be created. All one has to do is pick the next integer q when you get to 6q +5, and start over at 6q' +1
