Camera Help

I'm still new to Unity, and I'm developing a 2D game, in which the character has to jump from platform to platform until he reaches the top. I can make the camera follow the character, but I do not know how to centralize the camera in the scene, so the camera always takes the platform on which the character is and the other that he needs to jump. I need the camera to always adjust to get the current platform and the one I need to jump over. Can someone help me?
