How to Solve for n in Geometric Series EASY

This video provides a comprehensive guide on how to rearrange the geometric series sum formula to make n the subject. The formula Sn = a(rn - 1) / (r - 1) is a common requirement in Grade 12 mathematics, but isolating the variable n requires a solid understanding of both algebra and logarithms. We address the specific challenge of isolating an exponent. Many students struggle when the variable they need is "floating" in the power. We solve this problem by breaking down the algebra into simple steps, eventually using logarithms to bring n down. If you have ever felt overwhelmed by complex formulas or lost track of which operation to perform next, this walkthrough is designed for you. We show every single inverse operation, from clearing the denominator to applying log laws, ensuring that even the most struggling learner can follow along and succeed. Equations: Sn = a(rn - 1) / (r - 1) n = log(Sn(r - 1) / a + 1) / log(r) #mathhelp #maths #mathtutorial #examtricks #learnmath #mathematics #algebrahelp #strugglinginmath #BahulaClinton #geometricseries #sequencesandseries #logarithms #changeofsubject #grade12maths #matricmaths #southafricanmaths #algebra #solvingforn #mathslesson #sirguru #themotherboard #mathsplug #mathsguide #stepbystep #equations #rearrangingformulas #mathssolutions #mathskills #mathsteacher #studytips #mathshelpdesk #mathsexplained #mathsbasics #mathsvideo #mathsconcept #mathtricks #easymathtutorials #highschoolmath #learnmathsfast #mathsupport #masteringmath #mathproblems #algebraicmanipulation #mathhomework #mathstudy #mathematicsrules #solveforn #loglaws #mathsmasterclass #mathsfoundation #mathssuccess
