λ for one line of the hydrogen spectrum is .4118 x 104 cm. Use this value in the Rydberg equation to calculate the RH value using n1 = 2, and n2 = 6.

I assume the problem is telling us that the electron travels from N = 6 to n = 2 providing a wavelength of that value.
1/wavelength = R(1/2^2  1/6^2)
Solve for R. Wavelength must be in meters.
