What is the average of even numbers from 1 to 1371? Here we will show you how to calculate the average of even numbers from 1 to 1371.
To find the average of the even numbers from 1 to 1371, we first calculate how many even numbers there are from 1 to 1371. Then, we calculate the sum of even numbers from 1 to 1371. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 1 to 1371, and the even numbers within that range are from 2 to 1370. Therefore, the first even number in the sequence is 2, and the last even number in the sequence is 1370.
Step 1) Calculate the total number of even numbers from 1 to 1371
Here we calculate the total number of even numbers from 1 to 1371 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 = (1370 - 2 + 2) ÷ 2
tot = 1370 ÷ 2
tot = 685
Total even numbers from 1 to 1371 = 685
Step 2) Calculate the sum of even numbers from 1 to 1371
To calculate the sum of even numbers from 1 to 1371, 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 = (685 ÷ 2) × (2 × 2 + (2 × (685 - 1))
sum = 342.5 × (4 + 1368)
sum = 342.5 × 1372
sum = 469910
Sum of even numbers from 1 to 1371 = 469910
Step 3) Calculate the average of even numbers from 1 to 1371
Almost done! Now we can calculate the average of even numbers from 1 to 1371 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 = 469910 ÷ 685
Average = 686
Average of even numbers from 1 to 1371 = 686
