Surprisingly, it is called an ordered list of numbers!
It is an ordered sequence.
The middle value in a list of numbers is called the median. To find the median, you first arrange the numbers in ascending order and then identify the central value. If there is an odd number of values, the median is the middle one; if there is an even number, it is the average of the two middle values.

That's an infinite list.
A sequence.
