Question 1

How do you benefit from learning Geometric Progression formulas?

Accepted Answer

One of the significant benefits of understanding Geometric Progression formulas is the capability to quickly and accurately address simple formula-based questions.

Question 2

How to remember Geometric Progression formulas for a longer time?

Accepted Answer

Following are the techniques you can use to memorise Geometric Progression formulas:

For a start, you can start understanding the concepts of the Geometric Progression. It will help you find out why a formula is used.
Keep a separate piece of paper and write down each formula on the Geometric Progression topic you need to memorise.
Write down and examine each Geometric Progression formula, but this time with intervals. Write the equation, then take a 2-minute break to think about it before writing it again.
Your memory is more likely to associate with the formula you want to remember if you use it more often. Solve the problems employing the formula.
Visualise and repeat out loud the formula occasionally. Create Geometric Progression formulas flashcards to help with this. You can also use these flashcards while practicing the Geometric Progression questions.
The formula should be written down and posted somewhere you will see daily. They'll be subconsciously imprinted into your memory.

Question 3

How conceptual understanding of Geometric Progression topic helps in remembering its formulas?

Accepted Answer

Conceptual understanding will help you to make sense of the Geometric Progression formulas. Conceptual understanding is concentrated on describing why things happen as opposed to how to make them happen. They help you understand the true motive for employing the Geometric Progression formulas.

S.No	To Calculate	Formulas
1	General form of terms of a GP	$a, a r, a r^{2}, a r^{3}, . . . . a r^{n - 1}$
2	Common ratio	r = Common ratio = (Any term) / (Preceding term)
3	nth term of a GP	$a r^{n - 1}$
4	Sum of the first n terms of a GP (Sn)	$a [(r^{n} - 1) / (r - 1)] i f r \neq 1 a n d r > 1$ $a [(1 - r^{n}) / (r - 1)] i f r \neq 1 a n d r < 1$
5	Sum of a GP with infinite terms (Sn)	$a [(r^{n} - 1) / (r - 1)] i f r \neq 1 a n d r > 1$
