The average of the first 1815 natural numbers

Here we will define and show you the formula and the math to calculate the average of the first 1815 natural numbers.

The first 1815 natural numbers are the whole numbers (integers) that start with 1 and end with 1815. To make a list of the first 1815 natural numbers, you simply count up to 1815.

To get the average of those 1815 numbers, you add them up and then divide the sum by 1815. 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 = 1815 in our formula, we get the average of the first 1815 natural numbers. Here is the math and the answer:

avg = ((n × (n + 1)) ÷ 2) ÷ n
avg = ((1815 × (1815 + 1)) ÷ 2) ÷ 1815
avg = ((1815 × 1816) ÷ 2) ÷ 1815
avg = (3296040 ÷ 2) ÷ 1815
avg = 1648020 ÷ 1815
average = 908
