x = original value
0.5x = half of the original value = value after 1 year
0.5*(0.5x) = 0.25x = value after 2 years
0.5*(0.25x) = 0.125x = value after 3 years

Each time we progress year, multiply the previous value by 1/2 = 0.5

We end up with 0.125x which is 12.5% of the original value.
Note that 0.125 = 1/8 = (1/2)^3

Answer: 12.5%
