Correct answer: A
To calculate the three-yearly moving averages for the given series 15, 24, 18, 33, 42, 54, you need to find the average of each consecutive group of three values.
Here is the step-by-step breakdown:
Group 1: (15 + 24 + 18) / 3 = 57 / 3 = 19
Group 2: (24 + 18 + 33) / 3 = 75 / 3 = 25
Group 3: (18 + 33 + 42) / 3 = 93 / 3 = 31
Group 4: (33 + 42 + 54) / 3 = 129 / 3 = 43
The moving averages are 19, 25, 31, 43, which corresponds to Option 1.
