Number Sequences: Easy
IntellectualSpot the pattern and predict the next number in short numeric sequences — the foundation for harder sequence tests.
Overview
The Easy Number Sequences test introduces the numeric-pattern reasoning used in selection assessments. Every question draws from one of 13 sequence types — constant increases and decreases, second-degree progressions, alternating operations, Fibonacci-style recurrences, prime-gap increments, and a subtractive recurrence. Each question offers five multiple-choice options where the wrong answers represent plausible mistakes (off-by-one errors, wrong step size, wrong operation), so read each option carefully.
Assessments
Tested in assessments at KLM.
Could show up in Schuhfried, cut-e / Aon, DLR, ADAPT and SHL-based selections.
Airline mappings are based on public information and may change.
Example: what comes next?
Each item shows a number sequence ending in a blank. Work out the rule linking the terms, extend it one step, and pick the next value from the five options.
The gap between terms is a constant +3 (2→5→8→11), so the next value is 11 + 3 = 14. The distractors sit one or two steps off — checking that your rule reproduces every earlier term, not just the last, rules them out.

Choose your preferred duration before starting.
Solve
Identify the pattern in each sequence and pick the next number from five options as quickly and accurately as you can.
Review
After finishing, review your score and inspect each question and your answer.

The full progress test for number sequences — a mixed drill combining 30% easy, 40% medium and 30% hard sequence types to mirror the difficulty level of real pilot assessments.
Number Sequences: Medium
Step up from easy — interleaved sub-sequences, alternating operations, squaring and square roots mixed into harder numeric patterns.
Number Sequences: Hard
The toughest sequence test — tribonacci, prime-index jumps, interleaved fractions and powers, and multi-operation chains designed to mirror the difficulty level of real pilot assessments.
Letter Series
Spot the hidden rule in a row of letters and pick the next one — the letter analogue of number series, training serial induction on the alphabet.
