Answer:
d
Step-by-step explanation:
The sum to n terms of a geometric sequence is
= ![\frac{a(r^{n}-1) }{r-1}](https://tex.z-dn.net/?f=%5Cfrac%7Ba%28r%5E%7Bn%7D-1%29%20%7D%7Br-1%7D)
where a is the first term and r the common ratio
Here a = 3 and r = 12 ÷ 3 = 4 , thus
= ![\frac{3(4^{8}-1) }{4-1}](https://tex.z-dn.net/?f=%5Cfrac%7B3%284%5E%7B8%7D-1%29%20%7D%7B4-1%7D)
=
= 65536 - 1 = 65535 → d
