What three numbers have an average of 254?
Part 1: Understanding the Problem
We're looking for three numbers whose average is 254. This means if we add these three numbers together and divide by 3, we should get 254.
Step-by-step Solution:
- Recall the average formula: Average = (Sum of numbers) / (Count of numbers)
- In this case: 254 = (x + y + z) / 3
- To find the sum, multiply both sides by 3: 254 * 3 = x + y + z
- So, the sum of our three numbers should be: 762
Part 2: Finding Solutions
Now, let's find multiple sets of three numbers that add up to 762.
Solution 1:
254, 254, 254
Verification:
(254 + 254 + 254) / 3 = 762 / 3 ≈ 254
This solution is correct!
Solution 2:
254, 254, 254
Verification:
(254 + 254 + 254) / 3 = 762 / 3 ≈ 254
This solution is correct!
Solution 3:
216, 196, 350
Verification:
(216 + 196 + 350) / 3 = 762 / 3 ≈ 254
This solution is correct!
Solution 4:
272, 87, 403
Verification:
(272 + 87 + 403) / 3 = 762 / 3 ≈ 254
This solution is correct!
Solution 5:
216, 483, 63
Verification:
(216 + 483 + 63) / 3 = 762 / 3 ≈ 254
This solution is correct!
Explanation:
As you can see, there are many possible solutions. We can find more by:
- Choosing any two numbers
- Subtracting their sum from 762 to get the third number
Remember:
- The numbers don't have to be whole numbers.
- They can even be negative (although that might not make sense in some real-world contexts).
- The order of the numbers doesn't matter for the average.
