What is the sum of
2 raised to 0 ---------------------------------------2 raised to 2008
let s=20+21+--------------------22008 let s1=21+22+---------------22008 s1 is a geometric progression with a=2,r=2 & n=2008 so, s1=a(rn-1)/r-1 s1=2(22008-1)/2-1 = 22009-2 now, s=20+ s1=1+22009-2=22009-1.
let s=20+21+--------------------22008
let s1=21+22+---------------22008
s1 is a geometric progression with a=2,r=2 & n=2008
so, s1=a(rn-1)/r-1
s1=2(22008-1)/2-1 = 22009-2
now, s=20+ s1=1+22009-2=22009-1.
