Here we will define and show you the formula and the math to calculate the average of the first 3200 natural numbers.

The first 3200 natural numbers are the whole numbers (integers) that start with 1 and end with 3200. To make a list of the first 3200 natural numbers, you simply count up to 3200.

To get the average of those 3200 numbers, you add them up and then divide the sum by 3200. 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 = 3200 in our formula, we get the average of the first 3200 natural numbers. Here is the math and the answer:

avg = ((n × (n + 1)) ÷ 2) ÷ n
avg = ((3200 × (3200 + 1)) ÷ 2) ÷ 3200
avg = ((3200 × 3201) ÷ 2) ÷ 3200
avg = (10243200 ÷ 2) ÷ 3200
avg = 5121600 ÷ 3200
average = 1600.5
