There is no set formula for harmonic progression..

There isn't a good closed form expression.  As a special case, one has the Harmonic numbers

Hn=∑nk=11k.Hn=∑k=1n1k.

There isn't even a good closed form expression for this particular sum, although there is a good approximation 

Hn≈lnn+γ,Hn≈ln⁡n+γ,

where γγ is the Euler-Mascheroni constant.  Similar approximations can be given for more general sums of harmonic progressions.
