47 is 3 less than 50 & 56 is 6 more than 50. 3/50=0.06 or 3 is 6% of 50. Typically such crossover parts themselves have +,-10% deviation per value-as-marked tolerances which means the original resistor may have measured anywhere from 45 ohms to 55 ohms despite its' 50-ohm marking. So replacing a 50-ohm part with a 47-ohm part is not only OK, but within part specification. If only a 56-ohm part were available, even that will be fine but 47 is the slightly better choice of those two.
