Question

The sum of the terms of geometric sequence is called

Answer 1

Answer:

The sum of the first n terms of a geometric sequence is called geometric series.

Step-by-step explanation:

To find the sum of a finite geometric series, use the formula, Sn=a1(1−rn)1−r,r≠1 , where n is the number of terms, a1 is the first term and r is the common ratio .

Answer 2

Answer:-

 A geometric progression is also known as a geometric sequence, is a sequence of non-zero numbers.

If a sequence is geometric there are ways to find the sum of the first n terms, denoted by Sn,

To find the sum of the first $S_{n}$ terms of a geometric sequence use the following  formula

$S_{n} =\frac{a1(1-r^{n)} }{1-r} , r\neq 1$

where n is the number of terms, a1 is the first term and r is the common ratio.

The sum of the first n terms of a geometric sequence is called geometric series.
