For the given five values, 13, 17, 21, 22, 32; the 3-year moving averages are:

17, 20, 25

The correct answer is Option (4) → 17, 20, 25

Given values: 13, 17, 21, 22, 32

3-year moving averages:

First 3-year average: $\frac{13 + 17 + 21}{3} = \frac{51}{3} = 17$

Second 3-year average: $\frac{17 + 21 + 22}{3} = \frac{60}{3} = 20$

Third 3-year average: $\frac{21 + 22 + 32}{3} = \frac{75}{3} = 25$

3-year moving averages: 17, 20, 25
