The average will be the third number, because the first and fifth, as well as the second and fourth, will average out to the third.

The average is the sum of the numbers divided by the number of numbers:

If the odd numbers are 1, 3, 5, 7 and 9 the answer will be:

[tex] \frac{1+3+5+7+9}{5} [/tex]
[tex] \frac{25}{5} [/tex]
5 - 3rd number of the sequence.

The general answer (if using consecutive odd numbers) will always be the 3rd number of your sequence.


Hope it helped,

Happy homework/ study/ exam!
