The roots of the quadratic equation $\displaystyle 3 x^2-\mathrm{p} x+\mathrm{q}=0$ are $\displaystyle 10^{\text {th }}$ and $\displaystyle 11^{\text {th }}$ terms of an arithmetic progression with common difference $\displaystyle \frac{3}{2}$. If the sum of the first $\displaystyle 11$ terms of this arithmetic progression is $\displaystyle 88$ , then $\displaystyle \mathrm{q}-2 \mathrm{p}$ is equal to $\displaystyle \_\_\_\_$.
