(すうれつ)

すうれつ
noun
number sequence; numerical series
1. number sequence; numerical series; progression
An ordered list of numbers that follows a specific rule or pattern. A fundamental concept in mathematics, encountered in high school and university-level courses.
この数列(すうれつ)規則(きそく)()つけなさい。
Find the rule for this number sequence.
1, 1, 2, 3, 5, 8 はフィボナッチ数列(すうれつ)だ。
1, 1, 2, 3, 5, 8 is the Fibonacci sequence.
高校(こうこう)数学(すうがく)等差(とうさ)数列(すうれつ)等比(とうひ)数列(すうれつ)(なら)った。
I learned about arithmetic sequences and geometric sequences in high school math.

Composed of (すう) (number) and (れつ) (row, sequence). A standard mathematics term taught in Japanese high schools. The concept appears in entrance exams, puzzle books, and IQ tests, so the word is widely recognized even by non-mathematicians.
