The sum of ages of 5 children born at intervals of 3 years each is 50 years. What is the age of the youngest child?
Show Hint
In an arithmetic progression with an odd number of terms, the middle term is the average. Here, $50 / 5 = 10$ is the age of the 3rd child. Subtract $3 \times 2$ to find the youngest: $10 - 6 = 4$.
