A beam of light consisting of two wavelengths $\displaystyle 7000 \AA$ and $\displaystyle 5500 \AA$ is used to obtain interference pattern in Young's double slit experiment. The distance between the slits is $\displaystyle 2.5$ mm and the distance between the plane of slits and the screen is $\displaystyle 150$ cm. The least distance from the central fringe, where the bright fringes due to both the wavelengths coincide, is $\displaystyle n \times 10^{-5} \mathrm{~m}$. The value of $\displaystyle n$ is $\displaystyle \_\_\_\_$.
