Answer:
The median is 23
Explanation:
To find the median, you have to put the numbers in the set in order, then find the middle one.
Your set, ordered: 17, 18, 20, 26, 29, 35
And when they give you a set with an even number of entries, like this one, you average the two middle numbers. In this case, it's 20 and 26.
20 + 26 = 46
46/2 = 23
