Series Resistor Problem: Finding the Equivalent Resistance

The Attempt at a Solution

What I did was I knew that the their are two resistors in series

1/req= 1/R + 1/R = 1/2R

req= 2R

Where I get confused is how do I include the other resistor since I believe that it is in series?

The two resistors on the left are in parallel , that is the current splits up through the two branches before going through the last one.

Wow my addition was off... I figured it out, it is supposed to be 2/R and since like you said it splits up the total resistance would be req=R/2

R/2 +R = 3R/2

Got it.
