What is the average of odd numbers from 45 to 187? Here we will show you how to calculate the average of odd numbers from 45 to 187.
To find the average of the odd numbers from 45 to 187, we first calculate how many odd numbers there are from 45 to 187. Then, we calculate the sum of odd numbers from 45 to 187. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 45 to 187, and the odd numbers within that range are from 45 to 187. Therefore, the first odd number in the sequence is 45, and the last odd number in the sequence is 187.
Step 1) Calculate the total number of odd numbers from 45 to 187
Here we calculate the total number of odd numbers from 45 to 187 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 = (187 - 45 + 2) ÷ 2
tot = 144 ÷ 2
tot = 72
Total odd numbers from 45 to 187 = 72
Step 2) Calculate the sum of odd numbers from 45 to 187
To calculate the sum of odd numbers from 45 to 187, 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 = (72 ÷ 2) × (2 × 45 + (2 × (72 - 1))
sum = 36 × (90 + 142)
sum = 36 × 232
sum = 8352
Sum of odd numbers from 45 to 187 = 8352
Step 3) Calculate the average of odd numbers from 45 to 187
Almost done! Now we can calculate the average of odd numbers from 45 to 187 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 = 8352 ÷ 72
Average = 116
Average of odd numbers from 45 to 187 = 116
