Apparently you didn't notice that the two answers are different, and that the second will not work. Your original post stating "right and left hand" gives us the impressing that you have two parallel arpeggios set apart at a third.Anyways, to answer your question, for the RH 2-1-3-2-5-1-4-2-5-1-4-2-5-1 and so on, and the left hand would be 4-5-2-4-1-5-2-3-1-5-2-4-1-5. You begin by blocking the chords with the triad plus the octave, and then you break them using rotation. It is not so much the fingering that matters as long as you use the same one each time and you make active use of rotation in the forearm.By the way, your inability to provide an example indicates to me that you want to develop a general "technique" for such patterns. It won't work. As soon as you transpose it out of the key of C, the topography of the keyboard changes and so does the fingering. The technique is the same as that of a tremolo, there is just the added lateral motion and a different fingering.
