You can imagine an arrow in flight, toward a target. For the arrow to reach the target, the arrow must first travel half of the overall distance from the starting point to the target. Next, the arrow must travel half of the remaining distance. For example, if the starting distance was 10m, the arrow first travels 5m, then 2.5m. If you extend this concept further, you can imagine the resulting distances getting smaller and smaller. Will the arrow ever reach the target? if so, why? The arrow will never reach the target, and to explain it easier i will give an example. ex: 2.5/2= 1.25 1.25/2= .625 .625/2=.3125 .3125/2=.15625 .15625/2=.078125 ...continued... This will never end because the only way you can get 0 dividing by 2 is 0 divided by 2 which is impossible to get in this scenario, because no number above 0 can be divided by 2 to get 0.  i win |

The REAL answer goes like this. even if the numbers get smaller, it is still in infinant serise, and since any sum of an infinate serise will eventually equal a finite number, it will eventually get to 1, or the whole distance to the target so therefore the arrow hits the target. =p lol |

Three people check into a hotel. They pay £30 to the manager and go to their room. The manager suddenly remembers that the room rate is £25 and gives £5 to the bellboy to return to the people. On the way to the room the bellboy reasons that £5 would be difficult to share among three people so he pockets £2 and gives £1 to each person. Now each person paid £10 and got back £1. So they paid £9 each, totalling £27. The bellboy has £2, totalling £29. Where is the missing £1? ~100 gold~ its on the floor |
