FAQs on RS Aggarwal Class 11 Solutions Chapter-12 Geometrical Progression
1. What are some of the basic formulas of Geometric Progressions?
Geometric progressions are a sequence of non-zero numbers in which the ratio between two consecutive terms remain the same. Each element of the sequence is obtained by multiplying the previous term with a constant term called Common ratio.
The common ratio of a geometric progression is-
r = a2/a1
The formula for the nth term of a GP is:
aₙ = arⁿ⁻¹, where a is the first term of the GP and r is the common ratio.
The formula for the sum of a GP is:
Sₙ = a(1 - rⁿ)/(1 - r) , where a is the first term, r is the common ratio and n is the total number of terms.
