1+1/2+1/3+---------------+1/n

Dear Yuvraj

There is no correct simple general formula for sum of n terms of HP series

but the following formula will be a good approximation for sum to n-terms of the above series when n>5

S = 0.9973*ln(1.841*n + 0.6184)

Deviation from the actual value fluctuates but remains relatively low

All the best.
