For the given values 8, 10, 12, 14, 16; the three-year moving averages are:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 10, 12, 14
Given data: 8, 10, 12, 14, 16
Three-year moving averages:
First 3-year average: $\frac{8+10+12}{3} = \frac{30}{3} = 10$
Second 3-year average: $\frac{10+12+14}{3} = \frac{36}{3} = 12$
Third 3-year average: $\frac{12+14+16}{3} = \frac{42}{3} = 14$
