  Arithmetic sequence follows the order a,a+d,a+2d,a+3d….

  First term is a , a= 3

  Second term a+d= 7 . substitute a here to find d

  3+d=7, d=4

  Third term a+2d=11

  Fourth term a+3d=15

  We need to fifth,sixth and seventh term

  Fifth term a+4d= 3+4*4 = 19

  Sixth term a+5d = 3+5*4= 23

  Seventh term a+6d=3+6*4= 27

  The next three terms are 19,23,27
