Question

The smaller page number is
The larger page number is​

Answer 1

The smaller page number = 22

The larger page number = 23

Explanation:

Let the smaller page be x

The larger page number = x +1

x + ( x+1 ) = 45

2x + 1 = 45

2x = 45- 1 = 44

x = 44/2 = 22

The smaller page number = 22

The larger page number = 23
