1. To find :

   The common difference of A.P 307 , 323 , 339….

   Given :

   [tex]\huge\mathcal{x}[/tex]1 = 307

   [tex]\huge\mathcal{x}[/tex]2 = 323

   [tex]\huge\mathcal{x}[/tex]3= 339

   Formula :

   Common difference = [tex]\huge\mathcal{x}[/tex] 2-[tex]\huge\mathcal{x}[/tex]1

   Let’s solve :

   323-307 = 16

   [tex]\huge\mathcal{x}[/tex]3 -[tex]\huge\mathcal{x}[/tex]2 = 339-323 = 16

   Solution :

   16
