hey mate here is ur answer
a+3d+ a+7d=24
a+5d=12..........1.
a+5d+a+9d=44
a+7d=22..........2.
from equation 1.
a=12-5d........3.
put this value of a in equation 2.
we get ,
12-5d+7d=22
2d=10
d=5
put this value of d in equation 3 .
a=12-25
=-13
now 2nd term is a+d
-13+5=-8
and 3rd term is a+2d
-13+10
=-3
I hope it helps you
