What is the average of odd numbers from 1 to 2978? Here we will show you how to calculate the average of odd numbers from 1 to 2978.
To find the average of the odd numbers from 1 to 2978, we first calculate how many odd numbers there are from 1 to 2978. Then, we calculate the sum of odd numbers from 1 to 2978. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 2978, and the odd numbers within that range are from 1 to 2977. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 2977.
Step 1) Calculate the total number of odd numbers from 1 to 2978
Here we calculate the total number of odd numbers from 1 to 2978 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 = (2977 - 1 + 2) ÷ 2
tot = 2978 ÷ 2
tot = 1489
Total odd numbers from 1 to 2978 = 1489
Step 2) Calculate the sum of odd numbers from 1 to 2978
To calculate the sum of odd numbers from 1 to 2978, 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 = (1489 ÷ 2) × (2 × 1 + (2 × (1489 - 1))
sum = 744.5 × (2 + 2976)
sum = 744.5 × 2978
sum = 2217121
Sum of odd numbers from 1 to 2978 = 2217121
Step 3) Calculate the average of odd numbers from 1 to 2978
Almost done! Now we can calculate the average of odd numbers from 1 to 2978 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 = 2217121 ÷ 1489
Average = 1489
Average of odd numbers from 1 to 2978 = 1489
