How do we calculate average?
Average, which is the arithmetic mean, and is calculated by adding a group of numbers and then dividing by the count of those numbers. For example, the average of 2, 3, 3, 5, 7, and 10 is 30 divided by 6, which is 5.
How do I find the average of 6 numbers?
To calculate an average, add up all the terms, and then divide by the number of terms you added. The result is the (mean) average.
How do you find the average of unknown numbers?
First find the total of the four numbers (72 x 4 = 288). Then find the total of the two numbers that are given to you (68 + 70 = 138). Then find the total of the two unknown numbers (288 – 138 = 150). Divide that number by 2 to find the average of the two unknowns: 150 / 2 = 75.
How do I find a missing number?
Missing numbers are the numbers that got missed in the given series of numbers with similar differences among them….Missing Number Problems
- square = 1,
- square = 4 and then 4 – 1 = 3,
- square = 9,
- square = 16 and then 16 – 1 = 15,
- square = 25,
- square = 36 and then 36 – 1 = 35.
- square = 49.
How do you find the average of a list of numbers?
The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

What is the arithmetic mean of n natural number?
Find the arithmetic mean of the first 10 natural numbers. We also use that the sum of ‘n’ natural numbers is n(n+1)2 . Here, n=10 , which is the number of terms. Complete step-by-step answer: Sn=n2(1+n) . Hence, the sum of first n numbers is n(n+1)2 .
What is the first n natural numbers?
As we know natural numbers contain all the positive numbers starting from 1, 2, 3, to n numbers or infinity. For example, suppose when we calculate the sum of the first 25 numbers. That means we start adding the numbers from 1 to the given number 25, and the process is called the sum of the first N natural number.
