Verbal reasoning: letter and word sequences

Letter sequences follow a pattern of steps along the alphabet, often alternating or running two patterns at once. Write out the alphabet and count carefully.

What is tested

  • Letters moving by a fixed step
  • Two interleaved sequences
  • Letter and number combinations

Worked example

What comes next: B, D, F, H, ___?

  1. B to D is +2, D to F is +2, F to H is +2.
  2. H + 2 = J.

Answer: J

Exam-day checklist

  • Write out A to Z with numbers if needed.
  • Find the step between each pair.
  • If the step changes, look for two interleaved patterns.
  • Check you wrap around correctly after Z.

Common mistakes

  • Miscounting the steps.
  • Missing an alternating pattern.
  • Forgetting Z wraps to A.

Try it yourself

1. Next: A, C, F, J, ___?

Show answer

O

The steps are +2, +3, +4, so the next is +5: J + 5 = O.

2. Next: Z, X, V, T, ___?

Show answer

R

Each letter goes back 2 places.
