ISO increments on digital cameras are almost always one stop increments; 50, 100, 200, 400, 800, 1600, 3200, ... . Smaller increments, while possible, would be finer adjustments than necessary.
BTW, one stop increments in ISO and shutter speeds are double or half of the previous value so the increment between 800 and 1600 is the same as the increment between 100 and 200. Its a geometric progression and not a linear scale. With f/stops you multiply or divide by the square root of 2 (~1.414) to get one stop increments.
