Question

The left and page numbers of an open book are two consecutive integers whose sum is 259 find the page numbers

Answer 1

Answer:

$129$ and $130$

Step-by-step explanation:

Consecutive integers means $1,2,3,4,5...$ so on

That means we can model them as $x,(x+1),(x+2)...$

We are given the information that the sum of two consecutive integers is 259

so we can write

$x + (x+1)=259$

solving the above equation

$x+x=259-1$

$2x=258$

$x=\frac{258}{2}$

$x=129$

so the first page number of the book is 129 and the second is

$x+1$

$129+1$

$130$

Hence the page numbers are $129$ and $130$
