Atoms and Nuclei: JEE Main 2021 Physics question

The first three spectral lines of H-atom in the Balmer series are given $\lambda$₁, $\lambda$₂, $\lambda$₃ considering the Bohr atomic model, the wave lengths of first and third spectral lines $\left( \frac{\lambda_{1} }{\lambda_{3} } \right)$ are related by a factor of approximately 'x' $\times$ 10^$-$1. The value of x, to the nearest integer, is _________.
