What is the average of odd numbers from 4 to 162? Here we will show you how to calculate the average of odd numbers from 4 to 162.
To find the average of the odd numbers from 4 to 162, we first calculate how many odd numbers there are from 4 to 162. Then, we calculate the sum of odd numbers from 4 to 162. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 4 to 162, and the odd numbers within that range are from 5 to 161. Therefore, the first odd number in the sequence is 5, and the last odd number in the sequence is 161.
Step 1) Calculate the total number of odd numbers from 4 to 162
Here we calculate the total number of odd numbers from 4 to 162 by entering the first and last odd number in the sequence into our formula. Here is the formula and the math:
tot = (last - first + 2) ÷ 2
tot = (161 - 5 + 2) ÷ 2
tot = 158 ÷ 2
tot = 79
Total odd numbers from 4 to 162 = 79
Step 2) Calculate the sum of odd numbers from 4 to 162
To calculate the sum of odd numbers from 4 to 162, you enter the total odd numbers (tot) from Step 1 and the first odd number in the sequence into our formula. Here is the formula and the math:
sum = (tot ÷ 2) × (2 × first + (2 × (tot - 1))
sum = (79 ÷ 2) × (2 × 5 + (2 × (79 - 1))
sum = 39.5 × (10 + 156)
sum = 39.5 × 166
sum = 6557
Sum of odd numbers from 4 to 162 = 6557
Step 3) Calculate the average of odd numbers from 4 to 162
Almost done! Now we can calculate the average of odd numbers from 4 to 162 by dividing the sum of odd numbers from Step 2 by the total odd numbers from Step 1. Here is the formula, the math, and the answer:
Average = sum ÷ tot
Average = 6557 ÷ 79
Average = 83
Average of odd numbers from 4 to 162 = 83
