To determine the wavelength of a given line in the spec

To determine the wavelength of a given line in the spectrum of the analyzed sample, two lines in the spectrum of iron with wavelengths 373.713 and 374.566 were selected. The readings on the scale of the measuring microscope for these lines were 5.08 and 6.14, respectively. Determine the wavelength of a given line if the reading on the scale for it is 5.62
