I think I'm missing something- could you please explain how the cap would help me out here?

Hello, I am wondering what the highest recommended input impedance is when reading with the analog pins. I am planning to measure the voltage from 4xAA batteries with two 10K and one 2.2K to divide the voltage from 6V down to 3.3V. I'd like to scale up the resistors to say two 100K and one 22K...
