What does it mean "every other odd"? what's the difference with just "odd"?

Question

I am still learning english and I woul like to know what does that mean.

I need this for my intermediate algebra class.

Answer 1

You didn't give enough information for me to say for sure.

Odd numbers are: 1, 3, 5, 7, 9, 11, 13, and so on.

Every other odd number, would be where you miss one: 1, 5, 9, 13

However, if I had more information about what you're being asked I could be more sure this was the intended meaning.
