Hello all,
First of all, I apologize for the thread name. I'm not a native English speaker, nor did I ever have math class in English, so I don't know how to call this problem.
So I'll try to explain my problem as best as I can.
I have a base number, called "Y".
I have a standard multiplier, called "a",
The base number can be multiplied by a, but the result has to be added to the previous result. This process should be repeated X times.
X + aY + (a^2)Y + (a^3)Y + (a^4)Y ... etc
So for example using 10 as "Y", 1.1 as "a", and X = 3:
10 + 1.1*10 + (1.1^2)*10 +(1.1^3)*10 the outcome would be 46.41.
But how do I make a formula of this, where I can use X as a variable?
I hope I explained my question enough for you so you can understand what I mean.
Kind Regards,
Mark
