Question

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

Answer 1

Let the three consecutive odd integers be x, x + 2, x + 4

Given

The sum of three consecutive odd integers is 75

x + (x + 2) + (x + 4)  =  75

3x + 6  =  75

3x  =  75 - 6

3x  =  69

x  =  69/3

x  =  23

Hence,

First Integer : x = 23

Second Integer :  x + 2  =  23 + 2 = 25 

Third Intiger :  x + 4  =  23 + 4 = 27

Answer : 

Three Consecutive odd integers are 23, 25, 27.
