The average of the first 1388 natural numbers

Here we will define and show you the formula and the math to calculate the average of the first 1388 natural numbers.

The first 1388 natural numbers are the whole numbers (integers) that start with 1 and end with 1388. To make a list of the first 1388 natural numbers, you simply count up to 1388.

To get the average of those 1388 numbers, you add them up and then divide the sum by 1388. 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 = 1388 in our formula, we get the average of the first 1388 natural numbers. Here is the math and the answer:

avg = ((n × (n + 1)) ÷ 2) ÷ n
avg = ((1388 × (1388 + 1)) ÷ 2) ÷ 1388
avg = ((1388 × 1389) ÷ 2) ÷ 1388
avg = (1927932 ÷ 2) ÷ 1388
avg = 963966 ÷ 1388
average = 694.5
