If I remember well, there is a trick to calculate the sum of 1/2x from 1 to 
infinity
you just need a sheet of paper:
  + first you cut in half the sheet of paper: you get 1/2 sheet and another 
1/2 sheet
  + then you cut in half again one of the 1/2 sheet: you get 1/4 and 1/4
+  then you cut in half again...

so you can prove that 1/2+1/4+1/8+..+1/2n+.. = 1
