Answer 2

Answer:

7

Step-by-step explanation:

To Find: find the mean of first 7 odd natural numbers

Solution:

First 7 odd natural numbers: 1,3,5,7,9,11,13

Formula of mean : $\frac{\text{Sum of all observations}}{\text{Total number of observations}}$

So, mean of First 7 odd natural numbers:

$\frac{1+3+5+7+9+11+13}{7}$

$\frac{49}{7}$

$7$

Hence the mean of first 7 odd natural numbers is 7
