# What Is The Sum Of N Terms In GP?

## What is sum of geometric series?

Sum.

The sum of a geometric series is finite as long as the absolute value of the ratio is less than 1; as the numbers near zero, they become insignificantly small, allowing a sum to be calculated despite the series containing infinitely many terms.

The sum can be computed using the self-similarity of the series..

## What is the formula of sum of GP?

The nth term from the end of the GP with the last term l and common ratio r = l/ [r(n – 1)]. The sum of infinite, i.e. the sum of a GP with infinite terms is S∞= a/(1 – r) such that 0 < r < 1. If three quantities are in GP, then the middle one is called the geometric mean of the other two terms.

## What is the sum of first 25 terms of the geometric sequence 5 5 5 5?

The sum of the first 24 terms in the given geometric sequence is 0, so probably the sum of the first 25 terms is 5.

## What is the sum of the first seven terms of the geometric series?

2 Answers By Expert Tutors -15.875 is the sum of the first seven terms of the geometric progression. Every term in a geometric progression can be computed by multiplying together the term before it and the term after it and taking the square root of that.

## What is the nth term of a geometric sequence?

The nth term of a geometric sequence is a r n − 1 , where is the first term and is the common ratio.

## How many terms are there in the GP 3 6 12 24?

Here a = 3 and r = 6/3 = 2. Let the number of terms be n. => n-1 = 7 => n = 8….How many terms are in the G.P. 3, 6, 12, 24, ……., 384 ?A) -10B) 10C) -7D) 7

## What is the sum of an arithmetic sequence?

The terms between given terms of an arithmetic sequence. The sum of the terms of an arithmetic sequence. The sum of the first n terms of an arithmetic sequence given by the formula: Sn=n(a1+an)2.

## How do you find the sum of an N term in a geometric sequence?

The behavior of 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 − r .

## How do you find the number of terms in a GP?

How do you find the nth term of a geometric progression with two terms? First, calculate the common ratio r by dividing the second term by the first term. Then use the first term a and the common ratio r to calculate the nth term by using the formula an=arn−1 a n = a r n − 1 .

## What is the sum of finite GP?

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 .

## What is the formula of sum of n terms?

Sum of N Terms Formula It is equal to n divided by 2 times the sum of twice the first term – ‘a’ and the product of the difference between second and first term-‘d’ also known as common difference, and (n-1), where n is numbers of terms to be added.

## How many terms are there in the GP 5 10 20 40 1280?

Solution(By Examveda Team) Clearly, 5 x 2 = 10, 10 x 2 = 20, 20 x 2 = 40,….. So, the series is a G.P. in which a = 5 and r = 2. Let 1280 be the rath term of the series. Then, 5x2n-1 = 1280 ⇔ 2n-1 = 256 = 28 ⇔ n – 1 = 8 ⇔ n = 9.
