Answer 2

Answer:

40th term =87

Step-by-step explanation:

6th term=19 =a+5d=19-1st eq

17th term=41=a+16d=41-2nd eq

2nd eq-1st eq

a+16d=41

-a+5d=19

11d=22

d=22/11

d=2

subtitute d value in 1st eq

a+5(2)=19

a+10=19

a=19-10

a=9

so,40th term =a+39d

a=9,d=2

=9+39(2)

=9+78

=87

Therefore 40th term=87
