Number Sequences: Full Test
IntellectualThe 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.
Overview
The Full Number Sequences test combines every sequence type from the easy, medium and hard drills into one mixed practice session. Each set is drawn with a 30/40/30 split chosen to mirror the difficulty level of real pilot assessments: 30% easy types, 40% medium types, and 30% hard types split roughly 1:2.25 between the standard hard variants and the advanced set (tribonacci, prime-index progressions, interleaved fractional sub-sequences, power-of expressions, mixed numbers, multi-operation chains like *3-1 or /3/2-1). Every question offers five multiple-choice options where the wrong answers represent plausible mistakes. Take it as a Progression Test (a fixed set of sequences) to measure yourself against a target, or as a timed Open Challenge (10, 20, or 30 minutes) where your score feeds the Top Scores leaderboard.

Example: what comes next?
The Full test mixes easy, medium and hard sequence types in one run. Whatever the type, the task is the same: find the rule, extend it one step, and pick the next value from the five options.
The gaps grow by one each time: +1, +2, +3, +4. The next gap is +5, so 13 + 5 = 18. When the differences aren’t constant, look at how the differences themselves change — that second layer is where mixed tests hide the rule.
Game Phases
Configure
Pick a Progression Test (a fixed set of sequences) or a timed Open Challenge (10, 20, or 30 minutes).
Solve
Identify the pattern in each sequence and pick the next value from five options as quickly and accurately as you can.
Review
After finishing, review your score and inspect each question and your answer.
More Practice
Sequences
4 exercisesNumber Sequences: Easy
Spot the pattern and predict the next number in short numeric sequences — the foundation for harder sequence tests.
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.
