Short Answer 
The sequence “s p l o k f u p” is analyzed by identifying a pattern of forward and backward shifts in the alphabet. By applying specific shifting rules to each letter, it concludes with the final letter “o” completing the sequence.
Step 1: Identify the Pattern
The sequence “s p l o k f u p” is based on a specific pattern where each letter is shifted in the alphabet. To analyze it, we need to recognize the shifts involved‚ÄöAiboth forward and backward shifts are utilized. Each letter in the sequence is uniquely influenced by its position relative to the others.
Step 2: Apply the Shifting Rule
To determine the resulting letters based on shifts, we apply the following rules:
- From “s,” moving one position backward gives “r.”
- From “p,” moving forward results in “q,” and backward gives “o.”
- From “l,” moving forward gives “m,” and backward from “o” gives “n.”
- From “k,” one position forward results in “l,” and from “f,” moving backward gives “e.”
- From “u,” moving one position forward leads to “v,” and finally, from “p,” moving backward results in “o.”
Step 3: Conclude with the Final Letter
By applying these shifts consistently, we can conclude which letter completes the pattern. The final result from the shifting of “p” backward leads to the letter “o.” This confirms that the letter “o” is the one that successfully concludes the outlined sequence.
