About This Tool
A Fibonacci-like series follows the same recurrence rule as the Fibonacci sequence-each term is the sum of the previous two-but allows you to define the starting values. This tool makes it easy to experiment with custom sequences without any server-side processing.
Key Benefits
- Runs entirely in-browser with zero data collection
- Supports very large integers using BigInt
- Instant results with no network dependency
- Simple, distraction-free light-mode interface
Features
- Custom first and second terms
- Adjustable sequence length
- High-performance iterative computation
- Mobile-friendly and responsive layout
Use Cases
- Mathematics education and experimentation
- Algorithm design and testing
- Data pattern exploration
- Recreational math and learning
Fun Fact
Changing the starting values of a Fibonacci-like series can radically alter its growth behavior-yet the same simple recurrence rule always applies.
Historical Context
The classical Fibonacci sequence was introduced to Western mathematics by Leonardo of Pisa in the 13th century. Mathematicians later generalized the concept, recognizing that the recurrence relation itself-rather than the starting values-is the defining characteristic.
