What is "consecutive" anyways?
By consecutive we mean appearing one after the other. So for example 1,3,5 are consecutive odd integers.Again 7,9,11 are similarly 3 consecutive odd integers.
Now to the solution of the actual problem.
Let the three integers
be x,x+2,(x+2)+2 Notice in the example above how they differ by 2.
i.e. x,x+2 and x+ 4 are the 3 consecutive odd integers.
Given
=
=
=
Group the like terms
=
x=21
therefore the other 2 numbers are 23 and 25
Numbers are 21,23,25
