Question

If first term of GP is 'a' and the sum of first n terms is 'na' then
common ratio is
​

Answer 1

Answer:

The general form of an infinite geometric series is

: ∞∑n=0zn ∑ n = 0 ∞ z n .

the terms depends on the common ratio r .

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 −
