Oh... sorry i made a mistake. a n is Arithmetic progression! d=1/5

So is an

**arithmetic**progression of the form but what does "m" represent in your formula? - October 22nd 2013, 08:10 AMparmisRe: Geometric progression
I dont know. My teacher gave me this, but i cant answer it!

Then you should probably ask your teacher what means.

Assuming your arithmetic progression is since you arbitrarily wrote a d for some reason, we can set these two expressions equal to each other:

If you are trying to solve for , it is the solution to this quadratic equation in :

You can use the quadratic formula. You get a mess, but I suppose that could be the solution for ...
