Math Problem Statement

The left and right page numbers of an open book are two consecutive integers whose sum is 225. Find these page numbers.

Solution

To solve for the two consecutive page numbers whose sum is 225, we can denote the smaller page number as nn. Since the pages are consecutive, the next page number is n+1n + 1. The equation based on their sum is:

n+(n+1)=225n + (n + 1) = 225

This simplifies to:

2n+1=2252n + 1 = 225

Solving for nn, we subtract 1 from both sides:

2n=2242n = 224

Then, dividing both sides by 2 gives:

n=112n = 112

Therefore, the two page numbers are 112 and 113.
