What is a sequence?

• A. An ordered list of numbers
• B. A random set of numbers
• C. A single value
• D. A set with no order

Answer: (A)

A sequence is an ordered list of numbers (or objects) where the position of each term matters and there’s often a rule that generates the next term. The order is fixed from term to term, so a sequence like 2, 4, 6, 8 shows a clear pattern: each term comes after the previous one according to a rule (here, add 2). This differs from a random set of numbers, which doesn’t have a fixed order or a predictable rule. A single value isn’t a sequence by itself, and a set with no order isn’t a sequence either because a sequence relies on order and a rule to produce its terms. Sequences can be finite or infinite, continuing as long as the rule allows.
