Odd number series

.......

Answer 2

The mean of the given sequence of the first seven consecutive odd numbers is 7.

Given:

The sequence 1,3,5,7,9,11,13.

To Find:

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

Solution:

The mean of a given set of numbers is its average.

The mean is calculated by:

Mean = (Sum of all observations)/(Total number of observations).

We have been given a sequence 1,3,5,7,9,11,13 which is the list of the first seven consecutive odd numbers.

Let us find the sum of all given numbers.

The sum of all the observations = 1+3+5+7+9+11+13 = 49.

The total number of observations = 7.

Hence, mean = (Sum of all observations)/(Total number of observations).

⇒ Mean = 49/7 = 7.

∴ The mean of the given sequence of the first seven consecutive odd numbers is 7.
