# The average of the real parts of the nontrivial zeros of zeta function

 P: 99 greetings . i have come to find that the average of the real parts of the nontrivial zeros of the zeta function is : $$\bar{\sigma}=\lim_{n \to \infty }\frac{\gamma_{n-1} }{\gamma_{n}}-1$$ $\gamma_{n}$ being the nth Stieltjes Constant . now , i don't know how to evaluate the limit !! so any help is highly appreciated .
