a7=a1+6d=38
a9=a1+8d=37
subtract the second from the first
-2d=1
d=(-1/2)
substitute back in
38=a1+-3; a1=41
a7=38
a9=37
41+(-1/2)an is the sequence

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

1.  Wrong, incorrect, inaccurate formulation.
      It should be like this:
      ----------------------------------------
      the sum of the first seven terms of a linear sequence is 38 and the ninth term is 37. find the sequence ?
      ----------------------------------------

2.  Both solutions are wrong.
