Problema Solution
the room numbers of two adjacent classrooms are two consecutive odd numbers. If their sum is 808, find the classroom numbers.
Answer provided by our tutors
the two consecutive odd numbers can be written as
2x - 1 and 2x + 1, where x is integer
their sum is 808
(2x - 1) + (2x + 1) = 808
by solving we find
x = 202

2*202 - 1 = 404 - 1 = 403
2*202 + 1 = 404 + 1 = 405
the classroom numbers are 403 and 405.
