CAP Barbell Gray Olympic Cast Iron Weight Plate, 2.5-100 lb, Singles

Alternatively, you could just do the same weight twice in a row then go up 10 lbs. With accessories it's kind of up to you how to approach it as long as you are working hard. I would still increase the weight if you have hit the target reps.
