Comment on Greatest of 5 numbers

Great question.
Great question.
Since the mode is 4, we know that the first 3 numbers in the set are {4, 4, 5 ...}
At this point, the smallest integer we can add to the set is 6. If we were to add a number less than 5 then the median of the set will not be 5 (which is one of the requirements).
For example, if we add a 1, we get: { 1, 4, 4, 5, __} In this case, the median is 4.
Also, if we add another 5, we get: { 4, 4, 5, 5, __} In this case, the mode is 4 and 5.
So, in order for the median to be 5 and the mode to be 4, the next number we add must be greater than 5.
So, 6 is the smallest possible integer we can add to the set.

I'm not sure what else I would add to the original video.
Is there something in my written explanation that you feel isn't included in the video?
I'm not sure what's going on
couldn't you have 1,4,4,5,so final one is 26?
The median of {1, 4, 4, 5, 26
The median of {1, 4, 4, 5, 26} is 4. We need a median of 5.
