$20$

Step 1

Arrange the terms in ascending order.

20, 80

$20, 80$

Step 2

The median is the middle term in the arranged data set. In the case of an even number of terms, the median is the average of the two middle terms.

\frac{20 + 80}{2}

$\frac{20 + 80}{2}$

Step 3

Remove parentheses.

\frac{20 + 80}{2}

$\frac{20 + 80}{2}$

Step 4

Step 4.1

Factor

2

$2$ out of

20

$20$ .

\frac{2 \cdot 10 + 80}{2}

$\frac{2 \cdot 10 + 80}{2}$

Step 4.2

Factor

2

$2$ out of

80

$80$ .

\frac{2 \cdot 10 + 2 \cdot 40}{2}

$\frac{2 \cdot 10 + 2 \cdot 40}{2}$

Step 4.3

Factor

2

$2$ out of

2 \cdot 10 + 2 \cdot 40

$2 \cdot 10 + 2 \cdot 40$ .

\frac{2 \cdot (10 + 40)}{2}

$\frac{2 \cdot (10 + 40)}{2}$
