Answer 1

The symbols around the numbers in the list are absolute value bars.. they refer to the actual distance the number inside is away from "0" on a number line.  Since we always represent distance in positive terms, we can really assume the list will be  2,3, 7, 4....

the average of this list can be found by adding the 4 numbers and dividing by 4:
16 ÷ 4 = 4
