What is the average of odd numbers from 146 to 164? Here we will show you how to calculate the average of odd numbers from 146 to 164.
To find the average of the odd numbers from 146 to 164, we first calculate how many odd numbers there are from 146 to 164. Then, we calculate the sum of odd numbers from 146 to 164. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 146 to 164, and the odd numbers within that range are from 147 to 163. Therefore, the first odd number in the sequence is 147, and the last odd number in the sequence is 163.
Step 1) Calculate the total number of odd numbers from 146 to 164
Here we calculate the total number of odd numbers from 146 to 164 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 = (163 - 147 + 2) ÷ 2
tot = 18 ÷ 2
tot = 9
Total odd numbers from 146 to 164 = 9
Step 2) Calculate the sum of odd numbers from 146 to 164
To calculate the sum of odd numbers from 146 to 164, 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 = (9 ÷ 2) × (2 × 147 + (2 × (9 - 1))
sum = 4.5 × (294 + 16)
sum = 4.5 × 310
sum = 1395
Sum of odd numbers from 146 to 164 = 1395
Step 3) Calculate the average of odd numbers from 146 to 164
Almost done! Now we can calculate the average of odd numbers from 146 to 164 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 = 1395 ÷ 9
Average = 155
Average of odd numbers from 146 to 164 = 155
