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.
この数列の規則を見つけなさい。
Find the rule for this number sequence.
1, 1, 2, 3, 5, 8 はフィボナッチ数列だ。
1, 1, 2, 3, 5, 8 is the Fibonacci sequence.
高校の数学で等差数列と等比数列を習った。
I learned about arithmetic sequences and geometric sequences in high school math.
Composed of 数 (number) and 列 (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.
COMMON TYPES:
- 等差数列: arithmetic sequence (constant difference between terms)
- 等比数列: geometric sequence (constant ratio between terms)
- フィボナッチ数列: Fibonacci sequence
- 無限数列: infinite sequence
- 有限数列: finite sequence
COMMON COLLOCATIONS:
- 数列の和: sum of a sequence
- 数列の一般項: general term of a sequence
- 数列の収束: convergence of a sequence
SIMILAR WORDS:
- 級数: series — the sum of a sequence's terms
- 配列: array, arrangement — a more general ordering; also used in programming
- 順列: permutation — a different mathematical concept about ordering
