Determine the equivalent resistance of the circuit for R1 = R3 = R and R2 = R/2.

So you have R2 in parallel with R3. The equivalent resistance of resistors in parallel is:
1/Rt = 1/R1 + 1/R2 + 1/R3... Or for two resistors, it is Rt = (R1 * R2)/(R1 + R2).
So for this pair we have Rt = (R*R)/(R + R/2)
Rt = R²/(1.5R) = R/1.5 = (1/1.5)R = 0.66667R
Now add the single resistor in series. In series, Rt = R1 + R2 + R3...
So we have R + 0.66666R = 1.666667R
