The Solution:
Pattern A: start with 1 and add 3.
[tex]1,\text{ 4, 7, 10, 13}[/tex]
Pattern B: Start with 1 and add 4.
[tex]1,\text{ 5, 9, 13, 17}[/tex]
Comparing the two patterns, we have that:
Recall:
Median means the middle number.
The median of pattern A is 7 while that of pattern B is 9.
Thus, the median of pattern B is more than the median of pattern A by 2.
