Do not use an adapter. You need a properly wired outlet for a washing machine. A shock could kill you.
Change the outlet to a grounded one. Get an adapter that goes from 3 prong to 2. Break the ground prong off. Any one of these will work.
Yes, provided the outlet has a three element receptacle. The third prong is ground. If you use an adapter that connects three prongs to a two slot outlet there is a shock danger.
You should install a four prong. The older ones were three prong and had no ground. An adaptor isn't made because it wouldn't fix the problem. You could make your own adaptor and cut the ground off with a pair of dykes, but don't.
The four blade dryer plug brings a separate ground wire from the machine to the electrical grounding system. The three blade dryer plug depended on the neutral wire of the plug to make this connection.
It may be a 220 Dryer, and you will need a new outlet installed. There should be no extra wires when connecting the Power cord to the plug

Disregard the neutral

Buy a tester. They are very cheap and will tell you at a glance if the outlets are wired correctly. The only other way is to remove the outlet and look see. But if it is a 2 prong outlet with no ground hole then it does not have a ground.
call an electrician!!!
