Abstract: In this paper, we prove that for any finite dimensional vector space $ V$ over an algebraically closed field $ k$, and for any finite subgroup $ G$ of $ GL(V)$ which is either solvable or is generated by pseudo reflections such that $ \vert G\vert$ is a unit in $ k$, the projective variety $ \mathbb{P}(V)/G$ is projectively normal with respect to the descent of $ \mathcal O(1)^{\otimes \vert G\vert}$.
