Harver (NOA) Number Sequence Examples

Clear examples of number sequences in Harver (NOA)
The number sequence module in Harver (NOA) focuses on spotting the rule behind a series of numbers and extending it logically. Examples help set expectations before you begin practicing, especially if you want to understand the pace and the kind of pattern recognition involved.
The assessment may be used by employers in different sectors, and the exact composition can vary by organization. Even so, number sequences are one of the most common components, so it helps to get familiar with the format early.

What the examples are meant to show
The examples on this page are meant to illustrate the kind of reasoning used in number sequences, not to mirror a fixed test set. In practice, the pattern can involve simple arithmetic, alternating operations, skipping numbers, or combinations of these rules.
A useful way to approach these tasks is to look for changes between terms first, then check whether the same change repeats or alternates. If the pattern is not obvious, it often helps to test the sequence step by step rather than trying to guess the answer quickly.
- Start by comparing neighboring numbers.
- Check whether the rule changes every other step.
- Look for combined operations when the sequence seems to shift.
Common situations you may encounter
A sequence may grow by the same amount each time, but it can also move in a less direct way. For example, a set of numbers may follow a repeating pattern such as adding, then subtracting, or it may use a larger jump after a smaller one. The task is to identify the logic, not just the next number.
Some examples become more difficult because they mix operations. You may see a sequence where the numbers first increase and then the size of the increase also changes. In that case, it is important to track both the value and the size of each step.
You may also encounter patterns that rely on halving, doubling, or other straightforward arithmetic, especially when the sequence is designed to test accuracy under time pressure. Reading the pattern carefully matters more than moving fast at the start.
How to prepare with example-based practice
A steady preparation routine works best if you want to get comfortable with the format before the invitation arrives. Review a few example situations, then move into timed practice so you can learn how much time you can spend per item without losing accuracy.
- Study the structure of the sequence before looking at the answer choices.
- Work through a few untimed examples to recognize common patterns.
- Switch to timed practice once the logic feels familiar.
If you have received an invitation, keep an eye on your email and the Harver platform for additional instructions. The assessment details usually arrive there, and it is a good idea to begin practicing before the test date so the format feels familiar when you start.
Where this practice fits in the wider assessment
Harver uses NOA’s Cognitive Ability Assessment, and the most common components include number sequences, exclusion, and analogies. This module supports the numerical part of that assessment and is designed for candidates who want clear expectations before taking the test.
Because employers may use the assessment in different hiring processes, the best preparation is broad enough to cover the typical pattern types while still focusing on the sequence logic itself. That makes example-based practice useful whether you are new to the format or simply want a refresher.
