For the given five values $12,15,18,24,36$ ; the three-year moving averages are :

15,25,21

15,27,19

15,19,26

15,19,30

Correct Option: 3

First moving average:

\dfrac{12 + 15 + 18}{3} = \dfrac{45}{3} = 15

Second moving average:

\dfrac{15 + 18 + 24}{3} = \dfrac{57}{3} = 19

Third moving average:

\dfrac{18 + 24 + 36}{3} = \dfrac{78}{3} = 26

Therefore, the three-year moving averages are:

15, 19, 26
