Answer:
4th term =a+3d
6th ". "=a+5d
sum=2a+8d=24--(1)
a+5d+a+9d=2a+14d=44--(2)
(2)-(1)
14d-8d=20
6d=20
d=20/6
=10/3--(3)
substitute (3) in (1)
2a+8×10/3=24
2a=72/3-80/3
2a= -8/3
a= -16/3
so the first 3 terms are
-16/3,-6/3,4/3
hope this helps if so then don't forget to thank and mark as brainliest...... :)
