What is the average of even numbers from 5 to 94? Here we will show you how to calculate the average of even numbers from 5 to 94.
To find the average of the even numbers from 5 to 94, we first calculate how many even numbers there are from 5 to 94. Then, we calculate the sum of even numbers from 5 to 94. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 5 to 94, and the even numbers within that range are from 6 to 94. Therefore, the first even number in the sequence is 6, and the last even number in the sequence is 94.
Step 1) Calculate the total number of even numbers from 5 to 94
Here we calculate the total number of even numbers from 5 to 94 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 = (94 - 6 + 2) ÷ 2
tot = 90 ÷ 2
tot = 45
Total even numbers from 5 to 94 = 45
Step 2) Calculate the sum of even numbers from 5 to 94
To calculate the sum of even numbers from 5 to 94, 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 = (45 ÷ 2) × (2 × 6 + (2 × (45 - 1))
sum = 22.5 × (12 + 88)
sum = 22.5 × 100
sum = 2250
Sum of even numbers from 5 to 94 = 2250
Step 3) Calculate the average of even numbers from 5 to 94
Almost done! Now we can calculate the average of even numbers from 5 to 94 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 = 2250 ÷ 45
Average = 50
Average of even numbers from 5 to 94 = 50
