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,
.
