Do you know how to calculate resistance in series & parallel?

you have to use both here.
Step 1: resolve the resistance for the parallel component
Step 2: resolve the circuit in series

Like this? -im not sure which resistances to add together

No,

So first you have to solve the parallel loop

Which has 3 resistors, on one path: R and on the second path: 2R + 3R.

Once you've resolved the resistance for this section of the circuit you can add it back and consider it as one big resistor.
