HFM Number Sequence Examples and Practice
By the TestPrep editorial team · Updated
What to expect from HFM number sequence practice
The HFM number sequence module focuses on finding the rule behind a series of numbers and identifying the next value. In HFM assessments, this type of item often appears alongside other reasoning modules such as figure sequences, syllogisms, and analogies.
This guide gives you a clear picture of the kinds of patterns that can appear, so you can practice with the right expectations. The aim is not to memorize fixed formats, but to learn how to spot the logic more quickly under time pressure.
For HFM assessments, the exact mix of modules can vary by process. The invitation email provides the details, so it is useful to check that message carefully before you begin your preparation.

Common pattern types in number sequences
Number sequence questions usually rely on a small number of repeatable logic types. You may see simple arithmetic, alternating steps, or combinations of operations that only become clear after comparing several terms.
- Addition or subtraction with a consistent step
- Multiplication or division across the sequence
- Alternating rules, where different steps repeat in turn
- Patterns that combine two operations or change gradually
Concrete examples can be helpful when you are learning the method, even if the exact numbers are different in your actual test. Look for changes between nearby terms first, then check whether the same change repeats or shifts in a cycle.
How to approach a sequence methodically
A careful step-by-step approach helps when the rule is not obvious at first glance. Start by comparing the gaps between numbers, then test whether the sequence behaves like a simple arithmetic pattern or a more layered one.
If the sequence seems irregular, do not assume it is random. In assessment practice, many number sequences are built from a rule that becomes visible only after you examine pairs of terms, odd and even positions, or repeated changes across the full line.
Working this way also supports your timing. The more often you practice spotting structure quickly, the easier it becomes to move through the module without getting stuck on a single item.
Preparing for the HFM assessment with examples
Use practice examples to build familiarity with the kinds of reasoning HFM assessments often require. Because the test may be part of a broader selection or development process, balanced preparation is usually more effective than drilling one skill in isolation.
- Begin with easier sequences to confirm the basic rule before moving to harder combinations.
- Review each item after answering and note what pattern gave the sequence away.
- Practise under time pressure once you can solve examples with confidence.
The number sequence module is only one part of the wider HFM assessment. You may also encounter verbal or abstract reasoning tasks, and some processes include questionnaires that should be answered honestly and consistently.
