FAQs on RD Sharma Class 11 Maths Solutions Chapter 20 - Geometric Progressions
1. What is the GP formula?
Geometric progression refers to a series of non-zero numbers where each term of the series after the first term of the series is calculated by multiplying the previous term of the series by a fixed, non-zero number which is known as the common ratio. a, ar, ar2, ar3, and so on are the general type of a GP. Tn = arn-1 is the nth term in the GP sequence, where a = first term and r = general ratio = Tn-Tn-1). The sum of infinite terms of the S∞= a/(1-r) GP sequence, where 0< r<1. If a is the first term, r is a finite G.P. common ratio.
2. What is the definition of geometric progression?
In mathematics, geometric progression, also known as a geometric series, is a sequence of non-zero numbers where each term after the first is calculated by multiplying the previous one by a fixed, non-zero number called the common ratio. In simpler words, in a geometric progression, every term of the series bears a constant ratio to its preceding term. Therefore, to identify the terms of a geometric series, we only require the first term of the series and the constant ratio.
3. What's the sum of the infinite GP?
A geometric progression that contains infinite number of terms in its series can have two types of common ratios depending on the value of r, that is, if |r| < 1, and if |r| > 1. Therefore, the infinite geometric series that have a common ratio |r| < 1 has a sum equal to S = a/(1 - r).If you substitute rn with 0 in the overview formula, the 1-rn component will only be 1, and the numerator will only be a1. The formula for the number of an infinite geometric sequence is S∞=a1/ (1-r ).
4. What are the Properties of Geometric Progression?
There are certain properties that a Geometric progression follows are:
When the elements of a geometric progression are multiplied or divided by a fixed non-zero number, then the resulting sequence is also a geometric progression and has the same common ratio.
When all the terms of a geometric progression are reversed, then the reversed values also form a geometric progression.
When all the terms present in a geometric series are raised to a power of a specific number, then the series formed due to the mathematical operation also refers to a geometric progression.
For any three non-zero terms to behave like a geometric progression they need to fill the following criteria: y² = xz where x, y, and z are in a geometric progression.
