Answer:

25

Explanation:

We have 3 consecutive integers. Let's call the first one n.

The other two will then have the values of n+1 and n+2:

First number: n

Second number: n+1

Third number: n+2

Let's write the expression for the sum of these 3:


n + (n + 1) + (n + 2)


3n + 1 + 2\\


3n + 3

The sum, 3n+3, is equal to 78:


3n+3 = 78

Subtracting 3 from both sides:


3n = 75

Dividing both sides by 3:


n = 25

Now, let's find the values of our 3 numbers:

First number, n

n = 25, so our first number is 25.

Second number, n+1

n + 1 = 25 + 1 = 26, second number is 26

Third number, n+2

n + 2 = 25 + 2 = 27, third number is 27

Our 3 numbers are 25, 26, 27. The one closest to 0 is the smallest one, or 25.

Answer:

The answer is 25

Explanation:

What I would is to first divide 78 by 3. That will get you 26. Then add one to get 27, subtract one to get 25. 25+26+27=78

The answer is 25.
