Probability. Distribution function

Distribution function is $$D(x)=sum_{k=1, kgeq x}^{infty} 2^{-k}$$.
We need to find $mathbb{P}_D({14}cup{15})$ and $mathbb{P}_D([0,5])$.
1) So I think $mathbb{P}_D({14}cup{15})= mathbb{P}_D({14})+ mathbb{P}_D({15})=D(14)+D(15)$ Is it right?
2) What about $mathbb{P}_D([0,5])$?
$mathbb{P}_D([0,5])=D(5)-D(0)$?
is $D(0) = 0$?

Is that an increasing function of $x$?

From the sum it is not look like increasing function. This information is everything I have
