When I think about average with consecutive numbers, I think that it’s also the median. Let’s check.
If 12 is the median, there’s two numbers that are less than it and two that are more.
The list would be:
10, 11, 12, 13, 14
Let’s check to see if the average is 12. To find average, you have to add all the numbers together and then divide that number by the quantity of numbers in the list.
10+11+12+13+14=60
Now divide it by 5.
60/5=12
So, the largest number is 14.
