4. The sum of three consecutive positive integers is 54. What are these integers?

Solution:
Let the three consecutive integers be [tex]\( n \)[/tex], [tex]\( n+1 \)[/tex], and [tex]\( n+2 \)[/tex].

[tex]\[
n + (n+1) + (n+2) = 54
\][/tex]

Simplify and solve for [tex]\( n \)[/tex]:

[tex]\[
3n + 3 = 54
\][/tex]

[tex]\[
3n = 51
\][/tex]

[tex]\[
n = 17
\][/tex]

Thus, the integers are 17, 18, and 19.



Answer :

Certainly! Let's solve the problem step by step to find the three consecutive positive integers whose sum is 54.

1. Define the integers:
Let the three consecutive integers be [tex]\( n \)[/tex], [tex]\( n+1 \)[/tex], and [tex]\( n+2 \)[/tex].

2. Set up the equation:
The sum of these three consecutive integers is given as 54. Therefore, we can write the equation:

[tex]\[ n + (n+1) + (n+2) = 54 \][/tex]

3. Combine like terms:
Combine the [tex]\( n \)[/tex]'s together:

[tex]\[ n + n + 1 + n + 2 = 54 \][/tex]

[tex]\[ 3n + 3 = 54 \][/tex]

4. Isolate the variable [tex]\( n \)[/tex]:
To find [tex]\( n \)[/tex], we need to isolate it on one side of the equation. First, subtract 3 from both sides:

[tex]\[ 3n + 3 - 3 = 54 - 3 \][/tex]

[tex]\[ 3n = 51 \][/tex]

5. Solve for [tex]\( n \)[/tex]:
Now, divide both sides by 3:

[tex]\[ \frac{3n}{3} = \frac{51}{3} \][/tex]

[tex]\[ n = 17 \][/tex]

6. Find the consecutive integers:
Now that we have [tex]\( n \)[/tex], we can find the three consecutive integers:

[tex]\[ n = 17 \][/tex]
[tex]\[ n+1 = 17+1 = 18 \][/tex]
[tex]\[ n+2 = 17+2 = 19 \][/tex]

7. Conclusion:
Therefore, the three consecutive integers whose sum is 54 are [tex]\( 17 \)[/tex], [tex]\( 18 \)[/tex], and [tex]\( 19 \)[/tex].

So the solution to the problem is: The three consecutive integers are 17, 18, and 19.
