Three blocks are located on a horizontal table. The coefficient of kinetic friction between the blocks and the table is 0.276. They are connected by a massless cord, as shown in the figure below, and pulled to the right. The masses of the three blocks are = 9.0 kg, = 0.5 kg, and = 5.0 kg. The pulling force is equal to = 82.0 N. What is the tension ?

You don't provide or explain the figure. Are there cords between each block? Which cord to you want the tension of? Any cord that is being pulled with 82 N force has that same tension.
