Find the mean of the first 10 odd integers

To find the mean of the first 10 odd integers, we can follow these steps:

### Step 1: List the first 10 odd integers
The first 10 odd integers are:
\[ 1, 3, 5, 7, 9, 11, 13, 15, 17, 19 \]

### Step 2: Calculate the sum of these integers
Sum = \( 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 + 17 + 19 \)

\[
\text{Sum} = 100
\]

### Step 3: Divide the sum by the number of integers to find the mean
Mean \( \text{Mean} = \frac{\text{Sum}}{\text{Number of integers}} \)

\[
\text{Mean} = \frac{100}{10} = 10
\]

### Final Answer:
The mean of the first 10 odd integers is **10**.
