Hi. Anyone knows how to calculate the Req of this circuit? n tends to infinite. (Btw is there any sub forums for circuits only?)

PS - the numbers you see are based on ohm. like the resistor with "3" means a 3 ohm-resistor. (Numbers are the resistance value based on ohm)

While I don't know how to make an infinite series for this resistor network, it's simple enough to program a spreadsheet to find the equivalent resistance for any value of N. The network achieves its final value near 5 ohms at N=6, and won't vary from that value by more than a micro-ohm no matter how large N gets.
