Adinary Nuance
Sequence is close to order, series, and chain, but it strongly suggests a clear, connected order. Use sequence when the order matters, not just the number of items. A series can be a group without a strong fixed order, but a sequence always feels arranged. In academic English, sequence is common for steps, events, numbers, and scientific processes.
