Explanation:

 If three consecutive integers have sum 54 what is the smallest one?

A ) 17 ✅

B ) 18

C ) 21

D ) 22

RULE
Three consecutive integers:
Middle number = Sum ÷ 3
Smallest number = (Sum ÷ 3) − 1
Largest number = (Sum ÷ 3) + 1
Example:
Sum = 54
Middle = 54 ÷ 3 = 18
Smallest = 18 − 1 = 17
Largest = 18 + 1 = 19
Answer = 17
