a+9d = 11
a= 11-9d
it's 7th term = a+6d
put a = 11-9d
(11-9d)+6d= 11-9d+6d
-3d= -11
d=11/3.
put d = 11/3
a= 11-9d
a= 11-9×11/3=-22
Therefore,
a+6d = -22+6×11/3=-44.
Hence,
it's 7th term = -44
a= 11-9d
it's 7th term = a+6d
put a = 11-9d
(11-9d)+6d= 11-9d+6d
-3d= -11
d=11/3.
put d = 11/3
a= 11-9d
a= 11-9×11/3=-22
Therefore,
a+6d = -22+6×11/3=-44.
Hence,
it's 7th term = -44
