Question

what is the arithmetic mean of x,x+2,x+4,x+6,x+8

Answer 1

Hey there!

O_o One of the simplest formula for Calculating Arithmetic Mean is the following:

Add up all the numbers you want to average, and then divide by the number of items you just added.

ATQ,

x + x + 2 + x + 4 + x + 6 + x + 8/5

5x + 20/5

5(x + 4)/5

x + 4

Hence Arithmetic mean for the following question is x + 4 :)
