Alright, Lets look at this sequence. Is there anything you notice between the first two numbers?

How about...

$7-5=2$

Lets see if this continues to be true

$5-3=2$

$3-1=2$

So the pattern is that it is just adding two (or vise versa) to ever number in the sequence.

So if we continue it would look like...

$11, 9, 7, 5, 3, 1, -1, -3, -5, -7, -9$

Notice also that these are all odd!

Hope this helped!
