It will be about 10 euros and 20 cents to take the RER, which is way cheaper than a taxi and probably your cheapest option. You’ll have to take the RER from CDG to Chatelet-Les Halles the connect to the Metro A which will take you to La Defense (Grande Arche) All together it should take around 57 minutes.

I would take Les cars air france (bus – line 2 – green) directly to Charles de Gaulle Etoile and then take the RER A to La défense. It is maybe a little bit more expensive, but I prefer to spend time in a bus than in the RER
