Find the 10th and nth terms of the GP

Given GP is.


The given GP is of the form, a, ar, ar2, ar3….


Where r is the common ratio.


The first term in the given GP,


The second term in GP,


Now, the common ratio,



Now, nth term of GP is, an = arn – 1


So, the 10th term, a10 = ar9



Now, the required nth term, an = arn-1



Hence, the 10th term, and nth term,
.
