+2 +4 +8 +?

Answer 2

+ 16?
+ 32?
so 34 and 66, right?

Answer 3

Yes :) would that be arithmetic or geometric?

Answer 4

I'm not sure about that, how can I tell?

Answer 5

An arithmetic sequence goes from one term to the next by always adding (or subtracting) the same value.
A geometric sequence goes from one term to the next by always multiplying (or dividing) by the same value

Answer 6

no you don't add the same value every time
You multiply the number you add by 2 every time, so its geometric

I misread what you said, I see now.

Thank you very much.
