Is the sum of 3 consecutive whole numbers always divisible by 3. Explain?
Three consecutive whole numbers can be written as x, x + 1 and x + 2. Added together, their sum can be written as 3x + 3. Not only is that sum divisible by three, but by doing so [3(x + 1)] you can see that the sum is also equal to three times the second number.
What are three consecutive numbers who add up to 154?
There is no set of three consecutive whole numbers that add up to 154.
What are three consecutive numbers that add up to 68?
There are no such whole numbers. The sum of three consecutive whole numbers must be a multiple of 3; as 68 is not a multiple of 3 (68 = 3 × 22 2/3) it cannot be the sum of three whole numbers.
Can 3 consecutive whole numbers be primes?
No. Any three consecutive numbers will have at least one of them which is divisible by 2, which means it cannot be prime. And since 1 is not considered a prime number, it cannot happen.
Can three consecutive whole numbers all be prime?
Yes but the on prime numbers are 2,3
Can the sum of any three consecutive whole numbers be divisible by 6?
Yes, if the first number is odd.

Three consecutive whole numbers?
-3, -2 and -1.

What is always the sum of three consecutive whole numbers?
The sum of 3 consecutive whole numbers is always equal to 3 times the middle number in that sequence.
Can three consecutive whole numbers all be prime?
Yes but the on prime numbers are 2,3
What three consecutive whole numbers have a product of 29760?
The numbers are 30, 31 and 32.
Find three consecutive whole numbers such that the sum of the first two numbers equals the third number?
The three consecutive whole numbers you are looking for are 1, 2, and 3. The sum of the first two numbers, 1 + 2 = 3.
How many whole numbers from 100 to 999 are divisible by both 3 and 4?
