a man starts going for morning walk everyday. the distance walked by him on the first day was 2 km. Every day he walks half of the distance walked on the previous day. What can be the maximum total distance walked by him in his lifetime?
1) 4 km
2) 20 km
3) 8 km
4) Data inadequate

• this is the question of infinite GP SERIES
  here a=2 ,r=1/2
  
  sum=a/(1-r)
  = 2/(1-0.5)
  =4
  ans is 4 km
