If you first solve for a resistor pair, and then use the product over sum method for each additional resistor, it will still work, but it's just not the most straightforward way to go about it.

You can first solve for the first two; R

And then add in each additional resistor; R

You can first solve for the first two; R

_{1}*R_{2}/(R_{1}+R_{2}) = R_{12}And then add in each additional resistor; R

_{12}R_{3}/(R_{12}+R_{3})... … Read more
