Here we will define and show you the formula and the math to calculate the average of the first 6720 natural numbers.

The first 6720 natural numbers are the whole numbers (integers) that start with 1 and end with 6720. To make a list of the first 6720 natural numbers, you simply count up to 6720.

To get the average of those 6720 numbers, you add them up and then divide the sum by 6720. 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 = 6720 in our formula, we get the average of the first 6720 natural numbers. Here is the math and the answer:

avg = ((n × (n + 1)) ÷ 2) ÷ n
avg = ((6720 × (6720 + 1)) ÷ 2) ÷ 6720
avg = ((6720 × 6721) ÷ 2) ÷ 6720
avg = (45165120 ÷ 2) ÷ 6720
avg = 22582560 ÷ 6720
average = 3360.5
