In a container a mixture is prepared by mixing of three samples of hydrogen helium ion (He^(+)) and lithium ion (Li^(2+)). In sample , all the hydrogen atoms are in 1st excited state and all the He^(+) ions are in third excited state and all the Li^(2+)) ions are in fifth excited state. Find the total number of spectral lines observed in the emission spectrum of such a sample when the electrons return back to the ground state.

If Hydrogen like atom, the principal quantum number(excited) is 6,then find number of spectral lines.
