Heya !!!
This is your answer....
Given AP :::::----
27, 23, 19, ........, -65.
Here.....
a = 27.
l = -65.
d = 23 -27 = -4.
11th term from last term.... ???
There are two methods to solve it...
One is first find the number of terms and them subtract 11 from it. then By taking the result as n find the nth term.
But I will solve by another method which is simple and shortt....
We know that
an = a + (n-1) d
but here we have to obtain from last term...
so formula for it is......
an (from last term) = l - (n-1) d
Putting values....
a11 = -65 - (11-1)(-4)
= -65 + 40
a11 = -25.
Hence the eleventh term from last term is -25.
