To Find : 5th term from the end
Formulae :
As n = 12 , therefore there will be total (12 + 1) = 13 terms in the expansion
Therefore,
5 th term from the end = (13 - 5 + 1)th i.e. 9th term from the starting.
We have a formula,
= 495 (x)-4
Therefore,a 5th term from the end = 495 (x)-4
Conclusion : 5 th term from the end = 495 (x)-4
