Calculate Average: Finding Mean of 7 Numbers with Sum 28

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

• Step 1: Identify the given data
• Step 2: Use the average formula
• Step 3: Perform the division to find the average

Now, let's work through each step:

Step 1: The total sum of the numbers is given as $28$, and there are $7$ numbers.

Step 2: We'll use the formula for calculating the average:

$\text{Average} = \frac{\text{Sum of values}}{\text{Number of values}}$

Step 3: Plugging in the values, we have:

$\text{Average} = \frac{28}{7}$

$\text{Average} = 4$

Therefore, the solution to the problem is that the average of these seven numbers is $\mathbf{4}$.
