The sum of five consecutive numbers is 80. Find the largest number.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 18.
Let the five consecutive numbers be x, (x + 1), (x + 2), (x + 3), and (x + 4)
The sum of five consecutive numbers is 80
⇒ x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 80
⇒ 5x + 10 = 80
⇒ 5x = 70
⇒ x = 14
So, largest number = x + 4 = 14 + 4 = 18
