$\huge\red{ \bigstar} \huge{ \textbf{Sᴏʟᴜᴛɪᴏɴ}}$

Given,

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

To find,

The mean of 1, 3, 5, 7, 9, 11, 13.

Solution,

The mean of 1, 3, 5, 7, 9, 11, 13 is 7.

We can easily solve this problem by following the given steps.

Now, we know

Mean = Sum of all observations/total number of observations

Mean of the given data = 1+3+5+6+9+11+13/7 ( The total number of observations here is 7. If one more number will be given then it would be 8.)

Mean = 49/7

Mean = 7.

Hence,

• the mean of the first seven odd natural numbers is 7.

• (In class 11th, we learn about mean, median and mode in detail with their different formulas.)
