Question

Continue the sequence : 7,5,3,1?

Answer 1

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!
