Answer:

Step-by-step explanation:
<em>13 15 </em>17 <u>x</u> <em>20 21</em>
<em>Cross out all outer numbers</em>
We are left with 17 and x
With double medians, you add those two together and then divide them by two.
With the median (total) being 18, we will first add 17+x then divide Y/2 = 18
The value of x is 1
