Apply alternating +3, +2 shift: Computer : fqprxvht :: Language : ?

Difficulty: Medium

Correct Answer: ocqixcjg

Explanation:


Introduction / Context:
This problem features an alternating Caesar shift pattern: +3 on the first letter, +2 on the next, and so on. Detecting alternating shifts is a frequent theme in coding-decoding analogies.


Given Data / Assumptions:

  • “Computer” encodes to “fqprxvht”.
  • We must encode “Language” using the same alternating shift.
  • Alphabet index A=1 … Z=26 with wrap-around.


Concept / Approach:
Verify the alternation on the example, then apply +3 to positions 1,3,5,… and +2 to positions 2,4,6,… of “Language”. Keep letter order intact and wrap after Z if necessary.


Step-by-Step Solution:

Check “Computer”: c→f (+3), o→q (+2), m→p (+3), p→r (+2), u→x (+3), t→v (+2), e→h (+3), r→t (+2). Pattern confirmed.Apply to “Language”: L→O (+3), a→c (+2), n→q (+3), g→i (+2), u→x (+3), a→c (+2), g→j (+3), e→g (+2).Result: ocqixcjg.


Verification / Alternative check:
Decoding by alternating −3, −2 brings “ocqixcjg” back to “Language,” confirming the rule and application are correct.


Why Other Options Are Wrong:

  • oxpixdig/ocqicyig/ocqixcig: Each deviates at one or more positions from the strict +3, +2 alternation applied to the true letter values.


Common Pitfalls:
Losing track of the alternation after a few letters or misapplying +2 and +3 to the wrong positions. Mark odd and even positions clearly before computing.


Final Answer:
ocqixcjg
