Introduction to Consonant Series

Consonant Series problems involve sequences that consist only of consonant letters (all letters except A, E, I, O, U). These problems test your knowledge of the alphabet with vowels excluded and your ability to recognize patterns within the consonant set.

Prerequisites

Knowledge of vowels (A, E, I, O, U) Understanding that Y is a consonant in standard letter series Alphabet order with vowels removed Pattern recognition within consonant set
Why This Matters: Consonant Series problems appear in 1-2 questions in SSC CGL and Banking PO exams. They test understanding of alphabet classification.

How to Solve Consonant Series Problems

1

Step 1: Identify that vowels are excluded from the series

2

Step 2: Work with the consonant-only alphabet sequence

3

Step 3: Convert letters to positions in the consonant sequence

4

Step 4: Find the pattern (consecutive, skip, etc.) in consonant terms

5

Step 5: Apply the pattern to find the next consonant

6

Step 6: Convert back to the actual letter

7

Step 7: Verify the pattern holds for all given terms

Pro Strategy: Remove vowels from the alphabet to get the consonant sequence. Patterns in consonant series are similar to regular letter series but applied to the consonant-only alphabet.

Example Problem

Example: Find the next letter: B, C, D, F, G, ___ Solution: Step 1: Vowels A, E, I, O, U are excluded Step 2: Consonant order: B,C,D,F,G,H,J,K,L,M,N,P,Q,R,S,T,V,W,X,Y,Z Step 3: Given: B, C, D, F, G (consecutive consonants) Step 4: Next consonant after G is H Answer: H

Pro Tips & Tricks

  • Consonants: B, C, D, F, G, H, J, K, L, M, N, P, Q, R, S, T, V, W, X, Y, Z
  • 21 consonants total
  • After Z in consonant series, wrap to B
  • Vowels are A, E, I, O, U
  • Y is treated as a consonant in standard letter series
  • The gaps between consecutive consonants are not uniform (some skips due to vowels)

Shortcut Methods to Solve Faster

Consonant sequence: B,C,D,F,G,H,J,K,L,M,N,P,Q,R,S,T,V,W,X,Y,Z
After Z, next consonant is B (wrap)
Skip patterns in consonants are similar to regular skip patterns but applied to consonant list

Common Mistakes to Avoid

Including Y as a vowel
Forgetting that vowels are excluded
Using the full alphabet order instead of consonant order
Not accounting for vowel gaps in the sequence
