Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 21, 27, 35 **
Given values: 18, 25, 20, 36, 49
Three-year moving averages:
$\frac{18+25+20}{3} = \frac{63}{3} = 21$
$\frac{25+20+36}{3} = \frac{81}{3} = 27$
$\frac{20+36+49}{3} = \frac{105}{3} = 35$
The three-year moving averages are 21, 27, and 35.
