What is a Number List Generator?

A number list generator creates sequences of numbers based on specific patterns or rules. Whether you need a simple sequence from 1 to 100, the first 20 Fibonacci numbers, or a list of prime numbers, this tool can generate them instantly.

The generator supports various sequence types including sequential numbers with custom steps, even and odd number sequences, Fibonacci sequences, prime numbers, and power sequences (like powers of 2).

Advanced formatting options let you add prefixes, suffixes, pad numbers with zeros, and choose from different separators for your output.

Available Sequence Types

Sequential Numbers

Generate numbers in order with a custom starting point, ending point, and step value. Create sequences like 1-100, 0-1000 by 10s, or any custom range.

Even & Odd Numbers

Generate only even numbers (2, 4, 6...) or only odd numbers (1, 3, 5...) within your specified range or count.

Fibonacci Sequence

Generate the famous Fibonacci sequence where each number is the sum of the two preceding ones: 0, 1, 1, 2, 3, 5, 8, 13...

Prime Numbers

Generate prime numbers - numbers greater than 1 that are only divisible by 1 and themselves: 2, 3, 5, 7, 11, 13...

Frequently Asked Questions

How do I generate a specific count of numbers?

Enable the "Generate specific count instead of range" checkbox, then enter your starting number and the count of numbers you want to generate.

Can I add leading zeros to numbers?

Yes! Enable the "Pad with zeros" option and specify the total length. For example, with a pad length of 3, the number 5 becomes 005.

What is the maximum number I can generate?

For count-based generation, the limit is 10,000 numbers. For range-based generation, you can specify any range, but very large ranges may take longer to process.

How do I generate powers of 2?

Select "Powers" as the sequence type, set the base to 2, and choose your maximum power. This generates: 1, 2, 4, 8, 16, 32, etc.
