What is the average of even numbers from 5 to 152? Here we will show you how to calculate the average of even numbers from 5 to 152.
To find the average of the even numbers from 5 to 152, we first calculate how many even numbers there are from 5 to 152. Then, we calculate the sum of even numbers from 5 to 152. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 5 to 152, and the even numbers within that range are from 6 to 152. Therefore, the first even number in the sequence is 6, and the last even number in the sequence is 152.
Step 1) Calculate the total number of even numbers from 5 to 152
Here we calculate the total number of even numbers from 5 to 152 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 = (152 - 6 + 2) ÷ 2
tot = 148 ÷ 2
tot = 74
Total even numbers from 5 to 152 = 74
Step 2) Calculate the sum of even numbers from 5 to 152
To calculate the sum of even numbers from 5 to 152, 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 = (74 ÷ 2) × (2 × 6 + (2 × (74 - 1))
sum = 37 × (12 + 146)
sum = 37 × 158
sum = 5846
Sum of even numbers from 5 to 152 = 5846
Step 3) Calculate the average of even numbers from 5 to 152
Almost done! Now we can calculate the average of even numbers from 5 to 152 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 = 5846 ÷ 74
Average = 79
Average of even numbers from 5 to 152 = 79
