The correct answer is Option (2) → 40, 41.4, 43 **
Given data: 27, 35, 42, 45, 51, 34, 43
Five-year moving averages:
1st average (first 5 values):
$27+35+42+45+51 = 200$
$\text{MA}_1 = 200/5 = 40$
2nd average (values 2 to 6):
$35+42+45+51+34 = 207$
$\text{MA}_2 = 207/5 = 41.4$
3rd average (values 3 to 7):
$42+45+51+34+43 = 215$
$\text{MA}_3 = 215/5 = 43$
Five-year moving averages: 40, 41.4, 43
