Geometric Progression

A geometric progression is a sequence in which each term is found by multiplying the previous term by a fixed number, the common ratio $r$. Its $n$th term is $T_n=ar^{n-1}$, where $a$ is the first term.

For example $2, 6, 18, 54,\dots$ has $r=3$.

You meet Geometric Progression in the Progressions chapter of SPM Additional Mathematics. Knowing the term precisely matters in the exam: questions often hinge on reading a keyword correctly, and because SPM marking is analytic, using the right definition in your working helps secure method marks.

Our teachers make sure a student can not only recite what Geometric Progression means but use it fluently in a full solution.

Because the SPM Add Math paper is bilingual (BM/EN), it helps to know this term in each language: Geometric Progression (EN) · Janjang Geometri (BM) · 等比数列 (中文)
