I am a sequence of numbers where the next number is the sum of the two before me. What am I?

The Answer
The Fibonacci sequence
The riddle is literally the definition: 0, 1, 1, 2, 3, 5, 8, 13 — each term is the sum of the two that came before it. This is the Fibonacci sequence, discovered by 13th-century mathematician Leonardo of Pisa.

I move in a sequence, one to seven, then back to one, a loop that's never done. What am I?

The Answer
The days of the week
There are seven days in a week: Monday through Sunday. After Sunday, the cycle resets back to Monday — a loop that has repeated without end since the week was first defined. One to seven, endlessly cycling, is the calendar's heartbeat.

The Fibonacci sequence appears in many biological settings, such as the arrangement of leaves on a stem, the branching of trees, and the fruitlets of a pineapple.
A magic square is a grid of numbers where every row, column, and diagonal add up to the same total, and the oldest known example dates back to ancient China.
The number pi (π) is not only irrational but also transcendental, meaning it cannot be the root of any non-zero polynomial equation with rational coefficients.
In a group of just 23 people, there's a more than 50% chance that two people share the same birthday due to the birthday paradox.
Benford's Law states that in many naturally occurring collections of numbers, the leading digit is likely to be small, with the digit 1 appearing about 30% of the time.
Pascal's Triangle is not only a tool for expanding binomials but also displays patterns related to the Fibonacci sequence, prime numbers, and more.
The Mandelbrot Set, a famous fractal, is infinitely complex, and its boundary reveals self-similar patterns no matter how deeply you zoom in.
