Three continuous natural numbers, the smallest one is a, what is the sum of these three numbers?
The three numbers are: a + 1, a + 2
So the sum is: (a + 1) + A + (a + 2)
=3a+3
If there are three continuous natural numbers, the maximum of which is a, then the sum of the three numbers is a______ .
The three numbers are: A-2, A-1, a; A-2 + A-1 + a = 3a-3. A: the sum of the three numbers is 3a-3. So the answer is: 3a-3
