What is the average of even numbers from 3 to 178? Here we will show you how to calculate the average of even numbers from 3 to 178.
To find the average of the even numbers from 3 to 178, we first calculate how many even numbers there are from 3 to 178. Then, we calculate the sum of even numbers from 3 to 178. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 3 to 178, and the even numbers within that range are from 4 to 178. Therefore, the first even number in the sequence is 4, and the last even number in the sequence is 178.
Step 1) Calculate the total number of even numbers from 3 to 178
Here we calculate the total number of even numbers from 3 to 178 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 = (178 - 4 + 2) ÷ 2
tot = 176 ÷ 2
tot = 88
Total even numbers from 3 to 178 = 88
Step 2) Calculate the sum of even numbers from 3 to 178
To calculate the sum of even numbers from 3 to 178, 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 = (88 ÷ 2) × (2 × 4 + (2 × (88 - 1))
sum = 44 × (8 + 174)
sum = 44 × 182
sum = 8008
Sum of even numbers from 3 to 178 = 8008
Step 3) Calculate the average of even numbers from 3 to 178
Almost done! Now we can calculate the average of even numbers from 3 to 178 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 = 8008 ÷ 88
Average = 91
Average of even numbers from 3 to 178 = 91
