The product of the three consecutive odd numbers is 693. What is the sum of the largest and the smallest of the three numbers?
Show answer & explanation
Correct answer: A
Explanation
Given:
The product of three consecutive odd numbers = 693
According to the formula:
Let the numbers be = x−2, x, x+2
(x−2)·x·(x+2) = 693
x(x² − 4) = 693
7 × 9 × 11 = 693
The numbers are = 7, 9, 11
Sum (Smallest + Largest) = 7 + 11 = 18
