    Can you determine the convergence of this sum notation series for math homework?

    I think you are missing a sum at the beginning of all of that .. but I still don't know how you would go about solving that!

    Can you determine the convergence of this sum notation series for math homework?

    Homework Statement Determine whether series diverges of converges (conditionally or absolutely) (1+2)/(1+3) + (1+2+4)/(1+3+9) + (1+2+4+8)/(1+3+9+27) ... Homework Equations The Attempt at a Solution I'm assuming that I would have to put it into sum notation but I am struggling with that.

    Volume and Diameter Increase of Balloon in Stratosphere: Physical Chem Question

    Don't I need to consider pressure? So I would use p1*v1/t1=p2*v2/t2. But I would need to be able to calculate pressure difference based on height? Any idea on how to do that?
