Answer 1

First 50 whole numbers are 0, 1, 2, 3, 4 ... and 49.

Number of terms, N= 50
It is an even number.

$$\begin{gathered} \mathrm{Median}=\frac{1}{2}\left\{\left(\frac{N}{2}\right)\mathrm{th}\mathrm{observation}+\left(\frac{N}{2}+1\right)\mathrm{th}\mathrm{observation}\right\} \\ =\frac{1}{2}\left\{25\mathrm{th}\mathrm{observation}+26\mathrm{th}\mathrm{observation}\right\} \\ =\frac{1}{2}\left\{24+25\right\} \\ =24.5 \end{gathered}$$
