Three continuous natural numbers, the smallest one is a, what is the sum of these three numbers?

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
