Let the required page numbers are x and ( x + 1 ) ,





Given that the sum of page numbers is 517


According to the question :



= > x + ( x + 1 ) = 517

= > x + x + 1 = 517

= > 2x = 517 - 1

= > 2x = 516

[tex] = > x = \frac{516}{2} [/tex]

= > x = 258





Therefore,
Page numbers are ( x = 258 ) and ( x + 1 = 258 + 1 = 259 )
