The traditional advice is to dodge the question and make them name the first number. That advice works because they probably have a range in mind already. If you delay, they'll offer you something in the middle or lower part of that range, and you can negotiate them a bit up. If you name the first number and it's below or on the low end of their range, they will just accept and it will be worse for you.
