x^2+2x+c Hello anyone have this equation program plz send me to my mail Keertik.v7@gmail.com

hellp can anyone help for solution of this sum S=2+4+6+8+16+32+…..

Please can sent me to eraldguri@live.com

you are really good

I need in output 1+x+x^2+x^3+………

Why did you used x as an float?

since i used it as int and my result changed ony for x=5 and n=2 as 30 instead of 31!
