In the given problem, we need to find the 12th term from the end for the given A.P.
(i) 3, 5, 7, 9 …201
Here, to find the 12th term from the end let us first find the total number of terms. Let us take the total number of terms as n.
First term (a) = 3
Last term (an) = 201
Common difference (d) =
Now, as we know,
So, for the last term,
So, the 12th term from the end means the 89th term from the beg...
