Pattern Completion Dataset

A 30 GB synthetic dataset of numeric sequence‑completion prompts and their next values, designed to teach large language models how to recognize and extrapolate patterns.

Each row contains a prompt (the sequence with a ? indicating the missing next element) and a completion (the correct next number).

Dataset Structure

• Format: CSV (no header row)
• Columns:
  • prompt – "Find the next number in the sequence: a,b,c,... ,?"
  • completion – the correct next integer
• Total rows: ~405 million
• Uncompressed size: 30 GB
• Average row length: 74 bytes
• File: pattern_data.csv
