Title  Arc index of pretzel knots of type $(p,q,r)$ 
Abstract 
We computed the arc index for the pretzel knots $K=(p,q,r)$ with $p,q,r\geq 2$ and $r\geq q$, and at most one of $p,q,r$ is even. If $q=2$, then the arc index $\alpha(K)$ equals the minimal crossing number c(K). If $p\geq 3$ and $q=3$, then $\alpha(K)=c(K)1$. If $p\geq 5$ and $q=4$, then $\alpha(K)=c(K)2$.
