Question

if the first term of the GP is 16 and the common ratio is 3/2 then what will be the 4th term of the GP​

Answer 1

Answer:

Let the first term be a and the common ratio be r, then the n th term of the G.P. is given by a n=ar

n−1

. So, we have:

ar 3 =16, ar 6

=128

⇒r

3

=8⇒r=2,a=2

So, the first term and the common difference are both equal to 2.

its the answer..
