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