Theres a frog on one side of a road. The road is 10 metres wide. The forg's object is to get to the other side of the road. His first jump is 5m his second 2.5m and for every other jump he does the length halfs.

Eg:

1st-5m
2nd-2.5m
3rd-1.25m
etc

How many jumps will it take the frog to get to the other side? I don't actually know the answer and I ain't very good at maths in the vb environment but I would still be interested in the equation to find this answer out.

Thanx!
