2 answers
The irrational number that is between $\sqrt{14}$ and $\sqrt{18}$ can be approximated by finding the average of these two numbers: $$\frac{\sqrt{14} + \sqrt{18}}{2} \approx \frac{3.74 + 4.24}{2} = 3.99$$Therefore, a possible irrational number between $\sqrt{14}$ and $\sqrt{18}$ is $\boxed{\approx 3.99}$.
