What is the average of odd numbers from 1 to 6987? Here we will show you how to calculate the average of odd numbers from 1 to 6987.
To find the average of the odd numbers from 1 to 6987, we first calculate how many odd numbers there are from 1 to 6987. Then, we calculate the sum of odd numbers from 1 to 6987. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 6987, and the odd numbers within that range are from 1 to 6987. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 6987.
Step 1) Calculate the total number of odd numbers from 1 to 6987
Here we calculate the total number of odd numbers from 1 to 6987 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 = (6987 - 1 + 2) ÷ 2
tot = 6988 ÷ 2
tot = 3494
Total odd numbers from 1 to 6987 = 3494
Step 2) Calculate the sum of odd numbers from 1 to 6987
To calculate the sum of odd numbers from 1 to 6987, 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 = (3494 ÷ 2) × (2 × 1 + (2 × (3494 - 1))
sum = 1747 × (2 + 6986)
sum = 1747 × 6988
sum = 12208036
Sum of odd numbers from 1 to 6987 = 12208036
Step 3) Calculate the average of odd numbers from 1 to 6987
Almost done! Now we can calculate the average of odd numbers from 1 to 6987 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 = 12208036 ÷ 3494
Average = 3494
Average of odd numbers from 1 to 6987 = 3494
