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.

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌
