In Bohr’s hydrogen atomic model, the radius of the stationary orbit is directly proportional to n2.

The radius of Orbit

For an electron around a stationary nucleus, the electrostatic force of attraction provides the necessary centripetal force

\mathbf{r_{n} = 0.53 \frac{n^{2}}{z}A^{0}}

⇒  \mathbf{r_{n} \propto \frac{n^{2}}{z}}

From the above relation, the radius of the stationary orbit is directly proportional to n2.
