Calculate the Average: Finding the Mean of 2 and 6

Q: Why can't I just pick the number in the middle?

The middle number only works when numbers are evenly spaced. Between 2 and 6, the middle is 4, which happens to be the average. But try 1 and 10 - the middle is 5.5, but the average is also 5.5!

Q: What if I have more than two numbers?

The same formula works! Add all the numbers, then divide by how many numbers you have. For example: average of 2, 4, and 6 is $ \frac{2+4+6}{3} = \frac{12}{3} = 4 $.

Q: Does the order of numbers matter?

No! Addition is commutative, so 2 + 6 = 6 + 2. The average will always be the same regardless of the order you write the numbers.

Q: How do I know if my average makes sense?

Your average should always be between the smallest and largest numbers. If your answer is outside this range, you made an error!

Q: Can the average be a decimal?

Absolutely! If you're finding the average of 1 and 2, you get $ \frac{1+2}{2} = 1.5 $. Decimals are perfectly normal in averages.

Understand the problem

What is the average of $2$ and $6$ ?

Step-by-step solution

To solve this problem, we'll follow these steps:

Step 1: Identify the given numbers, which are $2$ and $6$ .
Step 2: Use the formula for the average: $\text{Average} = \frac{\text{Sum of terms}}{\text{Number of terms}}$ .
Step 3: Calculate the sum of the numbers: $2 + 6 = 8$ .
Step 4: There are two terms, so divide the sum by 2: $\frac{8}{2} = 4$ .

Now, let's work through each step:
Step 1: The given numbers are $2$ and $6$ .
Step 2: Using the average formula, we find that the average is the sum of the numbers divided by the number of numbers.
Step 3: Add the numbers: $2 + 6 = 8$ .
Step 4: Since there are 2 numbers, divide the sum by 2: $\frac{8}{2} = 4$ .

Therefore, the answer to the problem is $4$ .

Final Answer

Key Points to Remember

Essential concepts to master this topic

Formula: Average equals sum of numbers divided by count
Technique: Add 2 + 6 = 8, then divide by 2
Check: Verify answer falls between the two original numbers: 2 < 4 < 6 ✓

Common Mistakes

Avoid these frequent errors

Forgetting to divide by the number of terms
Don't just add the numbers and stop at 2 + 6 = 8! This gives you the sum, not the average. The average is always smaller than the sum when you have multiple numbers. Always divide the sum by how many numbers you added.
