well u can add them like this...

(2+2²+2³+2⁴+2⁵+2⁶...+2^n=2(2^(n+1)-1)

  +2²+2³+2⁴+2⁵+2⁶...+2^n=4(2^n-1)

        +2³+2⁴+2⁵+2⁶...+2^n=8(2^(n-1)-1)    

          :                             :  

          :                             :

            .                          2^n=2^n

-------------------------------------------  

                                         =n2^{n+1}-(2^(n+1)-2)=(2^(n+1))×(n-1)+2

=
