Question

The sum of first n terms of a Geometric sequence is 341 if a1=1/3 and a4=8/3 what is the value of n?​

Answer 1

Step-by-step explanation:

For r≠1 r ≠ 1 , the sum of the first n terms of a geometric series is given by the formula s=a1−rn1−r s = a 1 − r n 1 − r .

Answer 2

Step-by-step explanation:

to find the value of n we first need to find the ratio
