The mean of four numbers is 43. What are those four numbers?

42,43,43,44

Step-by-step explanation:

If there are four numbers in a list then the middle 2 numbers should be added up and divided up to give the mean. If we are given the mean we can now work backwards to give us:

(where x and y are the 2 middle numbers)

We can also see that x and y must be equal as the mean is an integer.

So:

So x=43 and that is the middle 2 numbers.

I don't exactly know how to explain how i got the other 2 numbers.
