HEY THERE ..!!
HERE IS YOURS SOLUTION;
◆ Given,
AP... 17,14,11..-40
So, now we need the 6th term from last. SO, by reversing the AP, we get;
AP = -40,-37,-31......14,17
Now, Given;
d=3
a1=-40
n=6
Therefore a6= a+(n-1)d
= a6= -40+(6-1)3
= a6= -40+5*3
= a6= -40+15
= a6= -25
★ So the 6th term is -25 ★
↓IF ANY DOUBT YOU CAN COMMENT DOWN↓
HOPE IT HELPS

The AP from the last: -40, -37, -34,..........., 17
a= 17.
d= a2 - a1
= -37-(-40)
= -37+40= 3
a6= ?
an= a+(n-1)d
a6= -40+(6-1) (3)
a6= -40+5(3)
a6= -40+15
a6= -25.
Therefore, the 6th term of the AP is -25.
