Let $\displaystyle \mathrm{S}_1$ be the sum of first 2n terms of an arithmetic progression. Let $\displaystyle \mathrm{S}_2$ be the sum of first 4n terms of the same arithmetic progression. If $\displaystyle \left(\mathrm{S}_2-\mathrm{S}_1\right)$ is $\displaystyle 1000$, then the sum of the first 6n terms of the arithmetic progression is equal to :
