During a training VFR cross country flight with a student we were climbing out of 4;500 to 5;500 FT; when the plane began to run extremely rough. I noticed that the EGT was reading 240 degree on the second cylinder. I knew at that point I lost a cylinder. I was receiving flight following from Approach; told them of the situation and I asked for the closest airport. I chose ZZZ as I was very familiar with it. I did not declare and emergency but they gave me priority. Landed without incident. I notified our repair shop and they flew out and concluded we had lost the #2 cylinder.
