Intelligence Test flashcards for Navy Sailor Test

21 of 50 cards from the Intelligence Test deck — real questions with worked answers.

1. In a number series, what is the rule of an arithmetic progression and how do you find the next term?

   In an arithmetic progression each term increases or decreases by a constant difference (d). The next term = last term + d. Example: 3, 7, 11, 15 has d = 4, so next is 19.

2. What defines a geometric progression in a number series, and how is the next term obtained?

   In a geometric progression each term is multiplied by a constant ratio (r). The next term = last term × r. Example: 2, 6, 18, 54 has r = 3, so next is 162.

3. In number series, what is a 'square series' and give an example?

   A square series lists perfect squares of consecutive numbers: 1, 4, 9, 16, 25, 36 (i.e., 1², 2², 3², 4², 5², 6²). The next term is the next perfect square.

4. What is a 'cube series' in number reasoning and give an example?

   A cube series lists perfect cubes of consecutive numbers: 1, 8, 27, 64, 125 (i.e., 1³, 2³, 3³, 4³, 5³). Next term is 216 (6³).

5. What is an alternating (mixed) number series and how is it solved?

   An alternating series interleaves two separate patterns in odd and even positions. Solve by splitting into two sub-series. Example: 1, 2, 4, 4, 7, 8 — odd terms (1,4,7) add 3; even terms (2,4,8) double.

6. How do you identify a 'prime number series'?

   A prime number series lists only primes in order: 2, 3, 5, 7, 11, 13, 17. Each term is a number divisible only by 1 and itself; the next term is the next prime.

7. What is the Fibonacci-type pattern in number series?

   Each term equals the sum of the two preceding terms. Example: 1, 1, 2, 3, 5, 8, 13 — here 5 = 2+3 and 8 = 3+5. The next term is 21.

8. In Coding-Decoding, what is 'letter-to-number coding' using positional values?

   Each letter is replaced by its position in the alphabet (A=1, B=2, ... Z=26). Example: CAB = 3-1-2. Reverse positions (Z=1) are also used: A=26, B=25 ... Z=1.

9. In Coding-Decoding, how does a 'letter-shift cipher' work?

   Each letter is moved forward or backward a fixed number of places in the alphabet. Example: with +1, CAT becomes DBU; with -1, DBU becomes CAT.

10. What is 'substitution coding' in Coding-Decoding problems?

    Whole words are replaced by other words by a fixed code language (e.g., 'sky is blue' = 'pa ka ta'). You decode by matching common words across multiple coded sentences to find each word's code.

11. In Coding-Decoding, what is the EJOTY rule and its use?

    EJOTY gives quick alphabet positions: E=5, J=10, O=15, T=20, Y=25. It helps rapidly recall a letter's number value (e.g., position of T is 20) for coding problems.

12. What is the opposite-letter (mirror) pairing of the alphabet used in coding?

    Each letter pairs with its opposite from the other end so the positions sum to 27: A-Z, B-Y, C-X, D-W, E-V, ... M-N. Example: opposite of C is X.

13. In reasoning, what is an Analogy and what does 'A : B :: C : ?' mean?

    An analogy expresses a relationship; 'A : B :: C : ?' means 'A is to B as C is to ?'. You find the relationship between A and B, then apply the same relationship to C to get the answer.

14. Give three common relationship types tested in Analogies.

    Common types: (1) cause and effect (e.g., germ : disease), (2) part to whole (e.g., wheel : car), (3) synonym/antonym, worker-tool, or function relationships (e.g., pen : write).

15. What is a 'number analogy' and give an example?

    A number analogy applies the same mathematical relationship to both pairs. Example: 2 : 8 :: 3 : 27, where the rule is cube (2³=8, 3³=27).

16. In Classification (Odd One Out), what is the task?

    You are given a group of items; all share a common property except one. The task is to identify the single item that does not belong to the group (the odd one).

17. Give an example of an Odd-One-Out based on a number property.

    In 4, 9, 16, 20, 25 — all are perfect squares (2²,3²,4²,5²) except 20, so 20 is the odd one out.

18. What strategy is used to solve word-based Classification problems?

    Identify the common category or property shared by most items (e.g., they are all fruits, or all even numbers), then pick the one that fails that property.

19. In Blood Relations, who are your 'maternal' relatives versus 'paternal' relatives?

    Maternal relatives are on the mother's side (maternal uncle = mother's brother, maternal aunt = mother's sister). Paternal relatives are on the father's side (paternal uncle = father's brother).

20. In Blood Relations, what does 'my father's only son' refer to (when spoken by a man)?

    It refers to the speaker himself. If a man has no brothers, his father's only son is himself.

21. Define these relations: brother-in-law and sister-in-law.

    Brother-in-law = your spouse's brother, or your sister's husband. Sister-in-law = your spouse's sister, or your brother's wife.
