Skip Letter Series

Skip Letter Series problems present sequences where each letter is obtained by moving a fixed number of steps forward (or backward) in the alphabet, skipping over a certain number of letters. For example, A, C, E, G (skip one letter between each). These problems test your ability to identify constant interval patterns in alphabetical sequences.

Introduction to Skip Letter Series

Skip Letter Series problems present sequences where each letter is obtained by moving a fixed number of steps forward (or backward) in the alphabet, skipping over a certain number of letters. For example, A, C, E, G (skip one letter between each). These problems test your ability to identify constant interval patterns in alphabetical sequences.

Prerequisites

Alphabet position knowledge Understanding of skip or gap concept Basic addition and subtraction Wrap-around handling for Z to A
Why This Matters: Skip Letter Series problems appear in 2-3 questions in SSC CGL and Banking PO exams. They test pattern recognition with fixed intervals.

How to Solve Skip Letter Series Problems

1

Step 1: Convert letters to position numbers (A=1 to Z=26)

2

Step 2: Calculate the difference between consecutive terms

3

Step 3: The difference should be constant (e.g., +2, +3, -2)

4

Step 4: Add the constant difference to the last term's position

5

Step 5: Handle wrap-around if position exceeds 26 or goes below 1

6

Step 6: Convert the resulting position back to a letter

7

Step 7: Verify the pattern holds for all given terms

Pro Strategy: The skip value is the number of positions moved forward minus 1 (e.g., skip 1 letter between = +2 positions). Always convert to numbers to find the exact skip pattern.

Example Problem

Example: Find the next letter: B, E, H, K, ___ Solution: Step 1: B=2, E=5, H=8, K=11 Step 2: Differences: +3, +3, +3 Step 3: Constant skip = +3 Step 4: Next position = 11 + 3 = 14 Step 5: Position 14 = N Answer: N

Pro Tips & Tricks

  • Skip of +2 means alternate letters (A, C, E, G...)
  • Skip of +3 means every third letter (A, D, G, J...)
  • Skip of +4 means every fourth letter (A, E, I, M...)
  • Negative skip moves backward (Z, X, V, T...)
  • Number of letters skipped between = skip value - 1
  • For wrap-around, add or subtract 26 to stay in 1-26 range

Shortcut Methods to Solve Faster

Skip +2 sequence: A, C, E, G, I, K, M, O, Q, S, U, W, Y
Skip +3 sequence: A, D, G, J, M, P, S, V, Y
Skip +4 sequence: A, E, I, M, Q, U, Y
Skip -2 sequence: Z, X, V, T, R, P, N, L, J, H, F, D, B

Common Mistakes to Avoid

Confusing skip value with number of letters skipped
Forgetting wrap-around when crossing Z or A
Not verifying the pattern with all given terms
Using addition when subtraction is needed for backward series
