The average of the first eight odd natural numbers is:
Ans 1. 10
2. 9
3. 8
4. 11

To find the average of the first eight odd natural numbers, we first list them:

1, 3, 5, 7, 9, 11, 13, 15

Next, we calculate their sum:
\[ 1 + 3 + 5 + 7 + 9 + 11 + 13 + 15 \]

Let's add them step-by-step:
\[ 1 + 3 = 4 \]
\[ 4 + 5 = 9 \]
\[ 9 + 7 = 16 \]
\[ 16 + 9 = 25 \]
\[ 25 + 11 = 36 \]
\[ 36 + 13 = 49 \]
\[ 49 + 15 = 64 \]

So, the sum of the first eight odd natural numbers is 64.

The average is the sum divided by the number of terms:
\[ \text{Average} = \frac{\text{Sum of terms}}{\text{Number of terms}} = \frac{64}{8} = 8 \]

Thus, the average of the first eight odd natural numbers is:

**3. 8**
