The average of 23, 24, 28 and 29 is_____.

Answer

To find the average of the numbers 23, 24, 28, and 29, we will follow these steps:

### Step 1: Add the numbers together
First, we need to calculate the sum of all the numbers:
\[ 23 + 24 + 28 + 29 \]

### Step 2: Calculate the sum
Now, let's perform the addition:
\[ 23 + 24 = 47 \]
\[ 47 + 28 = 75 \]
\[ 75 + 29 = 104 \]
So, the total sum is 104.

### Step 3: Count the number of observations
Next, we count how many numbers we have. In this case, there are 4 numbers (23, 24, 28, and 29).

### Step 4: Divide the sum by the number of observations
Now, we will divide the total sum by the number of observations to find the average:
\[ \text{Average} = \frac{\text{Sum of numbers}}{\text{Number of observations}} = \frac{104}{4} \]

### Step 5: Calculate the average
Now, let's perform the division:
\[ \frac{104}{4} = 26 \]

Thus, the average of the numbers 23, 24, 28, and 29 is **26**.
