Question:

For the given five values 16, 25, 19, 34, 46, the three years moving averages are

Options:

20, 26, 33

20, 26, 32

21, 25, 33

20, 25, 34

Correct Answer:

20, 26, 33

Explanation:

The correct answer is Option (1) → 20, 26, 33 **

Given values: $16,\;25,\;19,\;34,\;46$

Three–year moving average is computed by taking each group of three consecutive values and dividing their sum by 3.

First average:

$16 + 25 + 19 = 60$

$\frac{60}{3} = 20$

Second average:

$25 + 19 + 34 = 78$

$\frac{78}{3} = 26$

Third average:

$19 + 34 + 46 = 99$

$\frac{99}{3} = 33$

The three–year moving averages are 20, 26, 33.
