What is the average of even numbers from 3 to 162? Here we will show you how to calculate the average of even numbers from 3 to 162.
To find the average of the even numbers from 3 to 162, we first calculate how many even numbers there are from 3 to 162. Then, we calculate the sum of even numbers from 3 to 162. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 3 to 162, and the even numbers within that range are from 4 to 162. Therefore, the first even number in the sequence is 4, and the last even number in the sequence is 162.
Step 1) Calculate the total number of even numbers from 3 to 162
Here we calculate the total number of even numbers from 3 to 162 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 = (162 - 4 + 2) ÷ 2
tot = 160 ÷ 2
tot = 80
Total even numbers from 3 to 162 = 80
Step 2) Calculate the sum of even numbers from 3 to 162
To calculate the sum of even numbers from 3 to 162, 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 = (80 ÷ 2) × (2 × 4 + (2 × (80 - 1))
sum = 40 × (8 + 158)
sum = 40 × 166
sum = 6640
Sum of even numbers from 3 to 162 = 6640
Step 3) Calculate the average of even numbers from 3 to 162
Almost done! Now we can calculate the average of even numbers from 3 to 162 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 = 6640 ÷ 80
Average = 83
Average of even numbers from 3 to 162 = 83
