Answer

We know that going from n=4 to n=3 released less energy.

Work Step by Step

Light of wavelength 1875 nm is released when going from n=4 to n=3. Contrarily, the light emitted when going from three to one is less than 150 nm. Since shorter wavelengths correlate with higher energy, we know that going from n=4 to n=3 released less energy.
