if i have 3,4,6 as harmonic series..what is the harmonic mean ?

do i do it like sum of all terms / number of terms = (3+4+6)/3 =13/3

Or

do I reciprocate the things first to convert it into a AP i.e 1/3,1/4,1/6 are now in AP .....Now again I am stuck here because We are asked to find Harmonic mean , So do i calculate the Arithmetic mean i.e (1/3+1/6)/2or just mean by the formula sum of all terms / number of terms i.e (1/3+1/4+1/6)/3 ?

So, As you see I have messed up now ....whats the right direction ? I need explanation why I should choose one path and why to discard the other ?
