What is the average of even numbers from 50 to 168? Here we will show you how to calculate the average of even numbers from 50 to 168.
To find the average of the even numbers from 50 to 168, we first calculate how many even numbers there are from 50 to 168. Then, we calculate the sum of even numbers from 50 to 168. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 50 to 168, and the even numbers within that range are from 50 to 168. Therefore, the first even number in the sequence is 50, and the last even number in the sequence is 168.
Step 1) Calculate the total number of even numbers from 50 to 168
Here we calculate the total number of even numbers from 50 to 168 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 = (168 - 50 + 2) ÷ 2
tot = 120 ÷ 2
tot = 60
Total even numbers from 50 to 168 = 60
Step 2) Calculate the sum of even numbers from 50 to 168
To calculate the sum of even numbers from 50 to 168, 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 = (60 ÷ 2) × (2 × 50 + (2 × (60 - 1))
sum = 30 × (100 + 118)
sum = 30 × 218
sum = 6540
Sum of even numbers from 50 to 168 = 6540
Step 3) Calculate the average of even numbers from 50 to 168
Almost done! Now we can calculate the average of even numbers from 50 to 168 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 = 6540 ÷ 60
Average = 109
Average of even numbers from 50 to 168 = 109
