Median => 13

First arrange in ascending ya descending order

7, 9, 11, 13, 15, 17, 19

Second check how many number are there ( 7 ) if it is odd then choose middle number 13 that number is median

Second method

we can use median formula

1) if the number is odd :

$\bold{Median} = \frac{({n + 1)}^{th} }{2} term$

2) If number is even :

$\\ \frac{\frac{({n)}{th}}{2}term +( \frac{n}{2} + 1)^{th} }{2}$
