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

You have the sum of first eight terms of geometric progression with the first term 8 and the common ratio 2.

Use the formula for the sum of first n terms of geometric progression
(see the lesson Geometric progressions in this site)

S =  +  +  + . . . +  = 

     =  =  = 8*255 = 2040
