Find the mean of -12 and 28.

Answer

To find the mean of -12 and 28, we can follow these steps:

**Step 1: Identify the two numbers.**
The two numbers we need to find the mean of are -12 and 28.

**Step 2: Use the formula for the mean.**
The formula for the mean (average) of two numbers \( A_1 \) and \( A_2 \) is given by:
\[ \text{Mean} = \frac{A_1 + A_2}{2} \]

**Step 3: Substitute the values into the formula.**
Substituting -12 for \( A_1 \) and 28 for \( A_2 \):
\[ \text{Mean} = \frac{-12 + 28}{2} \]

**Step 4: Calculate the sum.**
Now, calculate the sum:
\[ -12 + 28 = 16 \]

**Step 5: Divide the sum by 2.**
Now, divide the sum by 2 to find the mean:
\[ \text{Mean} = \frac{16}{2} = 8 \]

**Final Answer:**
The mean of -12 and 28 is 8.
