What is the average of even numbers from 50 to 156? Here we will show you how to calculate the average of even numbers from 50 to 156.
To find the average of the even numbers from 50 to 156, we first calculate how many even numbers there are from 50 to 156. Then, we calculate the sum of even numbers from 50 to 156. And finally, we divide the sum by the number of even numbers to get the average.
The range is from 50 to 156, and the even numbers within that range are from 50 to 156. Therefore, the first even number in the sequence is 50, and the last even number in the sequence is 156.
Step 1) Calculate the total number of even numbers from 50 to 156
Here we calculate the total number of even numbers from 50 to 156 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 = (156 - 50 + 2) ÷ 2
tot = 108 ÷ 2
tot = 54
Total even numbers from 50 to 156 = 54
Step 2) Calculate the sum of even numbers from 50 to 156
To calculate the sum of even numbers from 50 to 156, 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 = (54 ÷ 2) × (2 × 50 + (2 × (54 - 1))
sum = 27 × (100 + 106)
sum = 27 × 206
sum = 5562
Sum of even numbers from 50 to 156 = 5562
Step 3) Calculate the average of even numbers from 50 to 156
Almost done! Now we can calculate the average of even numbers from 50 to 156 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 = 5562 ÷ 54
Average = 103
Average of even numbers from 50 to 156 = 103
