what are three consecutive odd integers whose sum is 75? write an equation and solve.

Question

how do you write an equation for 23,25,27

Answer 1

Hi Brittney--

 

Call the first integer n, and then the next two odd ones are n + 2 and n + 4.

 

Add them together to get 75:

 

n + n+ 2 + n + 4 = 75

 

which becomes 3n + 6 = 75

 

so 3n = 69, and n is therefore 23. n + 2 = 25, and n + 4 = 27.

 

Hope this helps!
