Question : The sum of three consecutive odd numbers is always divisible by ____.
Option 1: 3
Option 2: 9
Option 3: 15
Option 4: 21
Correct Answer: 3
Solution : Take any consecutive odd numbers i.e., 1, 3, 5 or 3, 5, 7 etc. Their sum = 1 + 3 + 5 = 9 which is divisible by 3. Again, the sum = 3 + 5 + 7 = 15 which is divisible by 3. So, the sum of three consecutive odd numbers is always divisible by 3. Hence, the correct answer is 3.
