Arithmetic Progression

An arithmetic progression is a sequence in which each term is found by adding a fixed number, the common difference $d$, to the previous term. Its $n$th term is $T_n=a+(n-1)d$, where $a$ is the first term.

Examples include $3, 7, 11, 15,\dots$ with $d=4$.

You meet Arithmetic 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 Arithmetic 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: Arithmetic Progression (EN) · Janjang Aritmetik (BM) · 等差数列 (中文)
