The sum of three consecutive odd integers is 243. Find the integers

Question

Solve the math problem 

Answer 1

Here's what we know:

a + b + c = 243

a = b - 2 (the first number is 2 less than the second)

c = b + 2 (the third number is 2 more than the second)

 

Plug in the variable values:

b - 2 + b + b + 2 = 243

Simplify:

3b = 243

Divide both sides by 3:

b = 81

 

You should be able to solve for a and c from here, and check your work.
