PRACTICE GUIDE VALKYRIE
Valkyrie Number Sequences Practice Test
This guide offers number sequences preparation for readers interested in Valkyrie Trading. The general practice ranges below are not a verified assessment specification for that employer.
Those are ranges across firms running this format rather than Valkyrie Trading's own figures, so treat them as the shape to train against and check the instruction screen on the day for the marking rule.
These are Outcry preparation topics, not a verified current firm assessment specification. Check your role-specific invitation for the test, timing, tools and recruitment stage.
Outcry is not affiliated with Valkyrie Trading and has no access to their assessment content. This guide describes an assessment format that candidates report publicly; the questions here are generated by Outcry and are not Valkyrie Trading’s own.
What it screens
A trading firm with public opportunities in trading and technology.
- ✓First and second differences, ratios, and alternating patterns
- ✓Interleaved sequences (two rules taking turns)
- ✓Squares, cubes, primes and factorials recognised on sight
- ✓Committing to an answer with seconds left
Where it sits at Valkyrie Trading
A trading firm with public opportunities in trading and technology. The topics here are Outcry preparation suggestions, not a verified firm syllabus or recruiting stage.
Outcry also has 4 other topic guides for readers interested in Valkyrie Trading. Their presence does not mean applicants must sit that many tests or that they belong to one recruiting round.

What it tests, with a worked example
Every example below is generated by Outcry, drawn from the same question generators the timed drills run. None of them is Valkyrie Trading’s.
Second-order differences
The differences themselves form a pattern - the give-away for a quadratic rule.
Example
Which one does not belong: 83, 16, 81, 49?
- 81
- 83
- 49
- 16
Answer 83
81, 49, 16 are all perfect squares. 83 is not.
Interleaved sequences
Two rules taking alternate turns, which reads as noise until you split the list.
Example 1
8, 16, 32, 64, 128, ? What comes next?
Answer 256
Each term multiplies by 2, so 128 × 2 = 256.
Example 2
43, 49, 55, 61, 67, ? What comes next?
Answer 73
Each term adds 6, so 67 + 6 = 73.
Example 3
9, 25, 57, 121, 249, ? What comes next?
Answer 505
Double and add 7: 249 × 2 + 7 = 505.
Named number families
Squares, cubes, primes, factorials and Fibonacci, recognised rather than derived.
Example 1
4, 14, 54, 214, 854, 3414, ?
Answer 13654
Each term is 4 times the last, minus 2. 4 × 3414 − 2 = 13654.
Example 2
6, 3, 18, 9, 54, 27, ?
Answer 162
Two sequences interleaved, both multiplying by 3. Positions 1, 3 and 5 run 6, 18, 54, so the next is 162.
Example 3
34, 38, 46, 58, 62, 74, ?
Answer 82
These are twice each prime, starting at 17. The gaps do not settle, which is the hint. The next prime after 37 is 41, so the answer is 82.
Operation chains
Each term built from the last by a repeating operation cycle rather than one rule.
Example 1
10, 15, 23, 34, 48, ? What comes next?
Answer 65
The gaps are 5, 8, 11, 14, growing by 3. Next gap 17: 48 + 17 = 65.
Example 2
11, 13, 17, 19, 23, ? What comes next?
Answer 29
Consecutive primes from 11. After 23 comes 29.
Example 3
1, 8, 27, 64, 125, ? What comes next?
Answer 216
Cubes from 1³. Next is 6³ = 216.
Committing under time
A sequence you cannot crack is a skip, not a guess, wherever the paper marks negatively.
Ratio runs that are not geometric
Terms whose ratios themselves move, which reads as geometric until the third term breaks it.
Example 1
11, 30, 68, 144, 296, ? What comes next?
Answer 600
Double and add 8: 296 × 2 + 8 = 600.
Example 2
34, 37, 40, 43, 46, ? What comes next?
Answer 49
Each term adds 3, so 46 + 3 = 49.
Example 3
9, 24, 54, 114, 234, ? What comes next?
Answer 474
Double and add 6: 234 × 2 + 6 = 474.
What a good score looks like
No current employer cutoff is verified for these general practice ranges. Use the worked examples to identify what to study and check your role-specific invitation for the actual assessment rules.
How to train for it
- 01Learn to take first and second differences automatically, before trying anything cleverer. It resolves most items on its own.
- 02Memorise the small squares, cubes, primes and factorials to sight-recognition. Deriving them is what costs the time.
- 03Give yourself a fixed budget per item and abandon at it. One sequence you refuse to let go of costs more than the three you never reach.

Common questions
- Is the Valkyrie number sequences test multiple choice?
- This guide uses typed next term for practice. The employer’s current answer format was not verified here.
- How long is the Valkyrie number sequences test?
- This guide uses general practice ranges of 20 to 30 questions in 10 to 25 minutes. They are not a verified current employer format.
- Is there negative marking on the Valkyrie number sequences test?
- It varies by firm and by year. Where a paper does mark negatively, skipping beats guessing; where it does not, answer everything. Check the instruction screen before you start - it is always stated there.
- How do I practise for it free?
- The warm-up drills are free with no account, and every pass opens the rest of the drills linked on this page. Questions are generated fresh each run, so there is nothing to memorise between attempts.
