Answer:
The sum of the first 8 terms in the series is 65535.
Step-by-step explanation:
We have,
The common ratio in a geometric series, r = 4
First term of GP is, a = 3
It is required to find the sum of the first 8 terms in the series. The sum of first n terms of a GP is given by :
[tex]S_n=\dfrac{a(r^n-1)}{r-1}, r>1[/tex]
Here, n = 8
[tex]S_8=\dfrac{3\times ((4)^8-1)}{4-1}\\\\S_8=65535[/tex]
So, the sum of the first 8 terms in the series is 65535.
