The average of the first 8 natural numbers

Here we will define and show you the formula and the math to calculate the average of the first 8 natural numbers.

The first 8 natural numbers are the whole numbers (integers) that start with 1 and end with 8. To make a list of the first 8 natural numbers, you simply count up to 8.

To get the average of those 8 numbers, you add them up and then divide the sum by 8. We created a formula that can calculate the average of any sequence of natural numbers starting with 1. Here is the formula to calculate the average (avg) of the first n natural numbers:

avg = ((n × (n + 1)) ÷ 2) ÷ n

When we enter n = 8 in our formula, we get the average of the first 8 natural numbers. Here is the math and the answer:

avg = ((n × (n + 1)) ÷ 2) ÷ n
avg = ((8 × (8 + 1)) ÷ 2) ÷ 8
avg = ((8 × 9) ÷ 2) ÷ 8
avg = (72 ÷ 2) ÷ 8
avg = 36 ÷ 8
average = 4.5
