Question

1.5.19

The room numbers of two adjacent classrooms are two consecutive odd numbers. If their sum is 920, find the classroom numbers
The classroom numbers are U (Use a comma to separate answers.)

Answer 1

I'm not sure what that U is for.

The answer is 459,461 These two do add to 920

Explanation:

Remark

I'm going to make sure you are using consecutive odd numbers.

Let the smaller number = 2x - 1

Let the larger number = 2x + 1

Equation

2x - 1 + 2x + 1 = 920

4x = 920

x = 230

The consecutive numbers are 2*230 - 1 = 459

and 2*230 + 1 = 461
