$\displaystyle =1-P(max(X_1,X_2,...,X_n)\leq\theta-\frac{x}{k_n})=1-[P(X_1\leq\theta-\frac{x}{k_n}]^n$

$\displaystyle =1-(1-\frac{x}{\theta k_n})^n$

How do I continue from here? What do they mean when they say $\displaystyle k_n$ is a sequence of constants?

Does it have anything to do with e^-x? If yes, then I guess I'm more or less get it.
