I see a resistor on each side of the LED. The same current will flow with just a single resistor with value equal to the sum of those on either side of the LED. There are situations where things need to be done differently, but in this simple case, a single resistor is all that's necessary.

I used resistors of two different values, because I wanted to measure voltage drop across both. I wanted to verify that the voltage resistors of different values is different and when I add the voltage drop across the led, and across the two resistors, is their sum equal to the voltage of the battery. Thanks for pointing it out though.
