Which term of the

Given GP is 3, 6, 12, 24….

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

Where r is the common ratio.

First term in the given GP, a1 = a = 3

Second term in GP, a2 = 6

Now, the common ratio,

Let us consider 3072 as the nth term of the GP.

Now, nth term of GP is, an = arn – 1

3072 = 3.2n – 1

n

2n = 211

n = 11

So, 3072 is the 11th term in GP.
