Harver tests / Number Sequences
Harver Number Sequences practice
Each row of numbers follows a rule. Pick the number, out of five, that replaces the question mark.
One full free game, then a Harver pass ($4.99 for 30 days, paid once) for unlimited practice. Built from Harver's own candidate help pages for this module. Harver does not publish its items, so all content here is ours.
How Number Sequences works
- A row of numbers ends in a question mark. Find the rule behind the row and pick the number that continues it.
- Every question has five options and only one is right. Click it to move on.
- Rules include adding or multiplying by the same amount, gaps that grow, two rules taking turns, and two rows woven together.
- Unconfirmed: the real number of questions and time limit. Practice uses 20 questions in eight minutes, getting harder as you go.
Time and scoring
8 minutes. Harver reports a score against other candidates: 50% is average and most people land between 30% and 70%. We have no comparison group, so practice shows your raw numbers.
Tips
- Write the differences between neighbours. If they are not equal, look at the differences of the differences, or at every second number.
- If the numbers jump fast, try multiplying rather than adding.
- Do not get stuck: answer, move on, and use the time on the questions you can solve.
Questions
What does the Harver number sequences test measure?
Harver groups it under numerical reasoning: spotting systems in rows of numbers.
Can I go back to a question?
Not known for the real test. In practice you cannot, so treat each answer as final.
