AI explanation

Three years ago, the sum of the father's and son's ages was 40 years. In the present year, their combined age increases by 2 * 3 = 6 years due to both people aging, making the current sum 46. After two more years, their combined age will increase by an additional 2 * 2 = 4 years. Adding this to the current sum gives 46 + 4 = 50.
