Number Pattern Generator
Generate mathematical number sequences including arithmetic, geometric, Fibonacci, prime, triangular, square, cube, and more. Customize length and parameters.
a, a+d, a+2d, … — each term increases by a fixed step (a = start, b = step)
About the Number Pattern Generator
Mathematical sequences are fundamental to number theory, computer science, and nature. Arithmetic sequences increase by a constant amount each step; geometric sequences multiply by a constant ratio. The Fibonacci sequence (1, 1, 2, 3, 5, 8…) appears throughout nature in spirals and growth patterns. Triangular numbers represent dots arranged in equilateral triangles. Prime numbers have no factors other than 1 and themselves. Use this generator to explore sequences, create datasets for testing, or teach mathematical concepts.
