Find the 5^th term from the end in the expansion of .

To Find : 5^th term from the end

Formulae :

•

•

For ,

a=x, and n=12

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. 9^th term from the starting.

We have a formula,

For t₉ , r=8

……….

Therefore, a 5^th term from the end

Conclusion : 5^th term from the end
