What is the average of odd numbers from 1 to 6420? Here we will show you how to calculate the average of odd numbers from 1 to 6420.
To find the average of the odd numbers from 1 to 6420, we first calculate how many odd numbers there are from 1 to 6420. Then, we calculate the sum of odd numbers from 1 to 6420. And finally, we divide the sum by the number of odd numbers to get the average.
The range is from 1 to 6420, and the odd numbers within that range are from 1 to 6419. Therefore, the first odd number in the sequence is 1, and the last odd number in the sequence is 6419.
Step 1) Calculate the total number of odd numbers from 1 to 6420
Here we calculate the total number of odd numbers from 1 to 6420 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 = (6419 - 1 + 2) ÷ 2
tot = 6420 ÷ 2
tot = 3210
Total odd numbers from 1 to 6420 = 3210
Step 2) Calculate the sum of odd numbers from 1 to 6420
To calculate the sum of odd numbers from 1 to 6420, 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 = (3210 ÷ 2) × (2 × 1 + (2 × (3210 - 1))
sum = 1605 × (2 + 6418)
sum = 1605 × 6420
sum = 10304100
Sum of odd numbers from 1 to 6420 = 10304100
Step 3) Calculate the average of odd numbers from 1 to 6420
Almost done! Now we can calculate the average of odd numbers from 1 to 6420 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 = 10304100 ÷ 3210
Average = 3210
Average of odd numbers from 1 to 6420 = 3210
