Question 648162: The room numbers of two adjacent classrooms are two consecutive odd integers. If their sum is 684 find the classroom numbers. Answer by DrBeeee(684) (Show Source):
You can put this solution on YOUR website! Let n = number of first classroom, then because the next room is the next consecutive odd integer;
(n+2) is the number of the second classroom.
We have
(1) n + (n+2) = 684 or
(2) 2n = 682 or
(3) n = 341
The next room is 343
Is (341 + 343 = 684)?
Is (684 = 684)? Yes
Answer: The room numbers are 341 and 343.
