Math Problem Statement

You can represent an odd integer with the expression 2n +1, where n is any integer. Write and solve an equation to find three consecutive odd integers that have a sum of 63.

Solution

We are asked to find three consecutive odd integers that have a sum of 63.

We can represent the three consecutive odd integers as:

  • The first odd integer: 2n+12n + 1
  • The second odd integer: 2n+32n + 3
  • The third odd integer: 2n+52n + 5

Now, let's set up an equation where the sum of these three integers equals 63:

(2n+1)+(2n+3)+(2n+5)=63(2n + 1) + (2n + 3) + (2n + 5) = 63

Step 1: Simplify the equation

Combine like terms:

2n+2n+2n+1+3+5=632n + 2n + 2n + 1 + 3 + 5 = 63

6n+9=636n + 9 = 63

Step 2: Solve for nn

Subtract 9 from both sides:

6n=6396n = 63 - 9

6n=546n = 54

Now divide by 6:

n=546=9n = \frac{54}{6} = 9

Step 3: Find the three consecutive odd integers

Now that we have n=9n = 9, substitute it back into the expressions for the three integers:

  • First integer: 2(9)+1=18+1=192(9) + 1 = 18 + 1 = 19
  • Second integer: 2(9)+3=18+3=212(9) + 3 = 18 + 3 = 21
  • Third integer: 2(9)+5=18+5=232(9) + 5 = 18 + 5 = 23

Conclusion:

The three consecutive odd integers are 19, 21, and 23.

To verify, their sum is:

19+21+23=6319 + 21 + 23 = 63

Thus, the solution is correct.
