WHAT IS THE ARITHMETIC MEAN OF 3, 5, 7, 9 AND 11
http://www.mathwarehouse.com/algebra/averages/
AM=(3+5+7+9+11)/5
AM=7
Just find the average of the terms.
In the given {3,5,7,9,11} what is the average?
To find the arithmetic mean of a set of numbers, you need to add up all the numbers and then divide the sum by the total count of numbers.
In this case, you want to find the arithmetic mean of 3, 5, 7, 9, and 11.
Step 1: Add up the numbers
3 + 5 + 7 + 9 + 11 = 35
Step 2: Divide the sum by the count of numbers
Since there are 5 numbers in the set, you divide the sum (35) by 5.
35 / 5 = 7
Therefore, the arithmetic mean (also known as the average) of 3, 5, 7, 9, and 11 is 7.
