I have a table with the following data.

New York 12 23 34
Washington 34 45 98

What i need is a update statement that copy Qty2 and update to Qty3 for each row as below:

City/Qty Qty1 Qty2 Qty3
New York 12 23 23

Well, based off the information provided,
UPDATE <tablename>
SET qty3 = qty2;

would seem to do the trick.
