Sum Formula of Geometric Series: Earlier in the lesson, a simpler shorthand for the nth term of a geometric sequence was described. The same can be done for a geometric series, with a little reasoning. First, for convenience, use Sn to denote the sum of the terms from 0 to n: Sn=∑...
Using geometric sum formula for finite terms,Sn = naSn = 34 × 1/5Sn = 6.8Answer: Geometric sum of the given terms is 6.8.Example 3: Find the sum of GP: 20, 60, 180, 540, and 1620, using the geometric sum formula. Solution:...
To calculate the partial sum of a geometric sequence, either add up the needed number of terms or use this formula. {eq}S_n = \frac{(a_1(1 - R^n)}{(1 - R)} {/eq} The sum of a series is denoted with a big S. The partial sum is denoted with the n subscript. The n is...

Since the ratio is constant, we confirm that this is a GP with a common ratio r=23. Step 3: Identify the first termThe first term a of the GP is:a=278 Step 4: Use the formula for the sum of the first n terms of a GPThe formula for the sum of the first n terms of a GP...
To find the sum of the first 6 terms of the given geometric progression (G.P.):Step 1: Identify the first term (a) and the common ratio (r). - The first term \( a \) is \( 3 \). - To find the common ratio \( r \), we can use th
This formula is appropriate for GP with r > 1.0. Sum of Infinite Geometric Progression, IGP The number of terms in infinite geometric progression will approach to infinity (n = ∞). Sum of infinite geometric progression can only be defined at the range of -1.0 < (r≠ 0) < +1.0 exclusi...
When the first and last terms are given, the formula of the sum of the first n terms of the arithmetic progression is given bySn = n/2 ( first term + last term )For example, let us use the previously given sum of the first 50 natural numbers. Since the given tells that the first...

Geometric progression (GP) is also termed as a geometric sequence. The formula which gives the sum of the infinite geometric sequence is given as, S=a1−r where a is the first term of the series, and r is the common ratio of the series. ...
