What is the average of even numbers from 1 to 339? Here we will show you how to calculate the average of even numbers from 1 to 339.
To find the average of the even numbers from 1 to 339, we first calculate how many even numbers there are from 1 to 339. Then, we calculate the sum of even numbers from 1 to 339. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 339, and the even numbers within that range are from 2 to 338. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 338.
Step 1) Calculate the total number of even numbers from 1 to 339
Here we calculate the total number of even numbers from 1 to 339 by entering the first and last even number in the sequence into our formula. Here is the formula and the math:
tot = (last - first + 2) ÷ 2
tot = (338 - 2 + 2) ÷ 2
tot = 338 ÷ 2
tot = 169
Total even numbers from 1 to 339 = 169
Step 2) Calculate the sum of even numbers from 1 to 339
To calculate the sum of even numbers from 1 to 339, you enter the total even numbers (tot) from Step 1 and the first even number in the sequence into our formula. Here is the formula and the math:
sum = (tot ÷ 2) × (2 × first + (2 × (tot - 1))
sum = (169 ÷ 2) × (2 × 2 + (2 × (169 - 1))
sum = 84.5 × (4 + 336)
sum = 84.5 × 340
sum = 28730
Sum of even numbers from 1 to 339 = 28730
Step 3) Calculate the average of even numbers from 1 to 339
Almost done! Now we can calculate the average of even numbers from 1 to 339 by dividing the sum of even numbers from Step 2 by the total even numbers from Step 1. Here is the formula, the math, and the answer:
Average = sum ÷ tot
Average = 28730 ÷ 169
Average = 170
Average of even numbers from 1 to 339 = 170
