Resistor 1 ---26.6 ohm Resistor 2 --- 329 ohm

Calculated value 1&2 in series R1=27 ohm, R2=330 ohm______total R1+R2=357 ohm

Mesured value 1&2 in series 356 ohm

Calculated value 1&2 in parallel 25 ohm 1/R1+1/R2=1/Rt

Mesured value 1&2 in parallel 24.6 ohm

Explanation:

In series circuits total resistance adds together, but in parallel circuits total resistance lower then lowest resistor.
