Hi ,
27 , 23 , 19 , ... , -65 is an A.p
First term = 27
Common difference = a2 - a1
d = 23 - 27
d = - 4
Rearranging the A.P in reverse order ,
-65 , -61 , -57 , ... , 19 , 23 , 27 is an A.P
a = - 65 , d = 4
11th term = a11
= a + 10d
= -65 + 10 × 4
= -65 + 40
= - 25
11th term from the last is = -25
I hope this helps you.
