Percentage change can be determined by dividing the change by the quantity of the base year. The base year here is year 1, so we use the value of $410,000 as base price.
Year 2:
Percentage change = ($460,000-$410,000)/$410,000*100 = 12.2%
Year 3:
Percentage change = ($510,000-$410,000)/$410,000*100 = 24.4%
The percentage change increased doubly.
