Introduction to Nth From End
Nth From End problems require you to find the letter that occupies a specific position when counting from the right end (Z) or left end (A) of the alphabet. These problems test your understanding of bidirectional alphabet sequencing.
Prerequisites
How to Solve Nth From End Problems
Step 1: Identify whether counting is from left end (A) or right end (Z)
Step 2: Note the position number n given in the problem
Step 3: If counting from left end, the answer is simply the nth letter (A=1st, B=2nd, etc.)
Step 4: If counting from right end, calculate: position = 27 - n
Step 5: Convert the calculated position number to the corresponding letter
Step 6: Verify by manually counting from the specified end
Step 7: Answer the question with the identified letter
Example Problem
Example 1: What is the 5th letter from the right end of the alphabet? Solution: Step 1: Counting from right end (Z is 1st from right) Step 2: n = 5 Step 3: Position from left = 27 - 5 = 22 Step 4: 22nd letter = V Answer: V Example 2: What is the 12th letter from the left end? Solution: Step 1: Counting from left end (A is 1st) Step 2: n = 12 Step 3: 12th letter = L Answer: L
Pro Tips & Tricks
- From left: nth letter = position n directly
- From right: nth letter = letter at position (27 - n)
- The 1st from right is Z (position 26), 2nd is Y (25), and so on
- Create a quick reference: 1st right=Z, 2nd=Y, 3rd=X, 4th=W, 5th=V
- For quick calculation, 27 minus position gives left position
- Practice with pairs: 1st left = A, 1st right = Z; 13th left = M, 13th right = N
