If x represents the son's age two years ago, then the son is currently x + 2 years old.
Two years ago, the father was four times as old as his son, so the father was 4(x).
To determine the current age of the father, we need to add two years to the father's age two years ago (4x + 2).
Three years from now, the father will be (4x + 2) + 3 = 4x + 5 years old.
Therefore, the expression that represents the father's age three years from now is 4x + 5.
