Question
Find the median of the following:
3x, x+5, x+7, x+9, x+11, x+13
Solution
3x, x+ 5, x+7, x+9, x+11, x+13
Arranging the given data in descending order:
x +13, x+ 11, x+9, x+7, x+5, 3x
The middle terms are x +9 and x+7 which are 3rd and 4th terms
median = `(x+9+x+ 7 )/2 = (2x+16 )/2 = x + 8`
Therefore, Median = x+8.
