The key idea

Understand the rule first

Write alphabet positions and differences. If one step does not repeat, split odd and even terms or test an alternating pattern, remembering that sequences may wrap after Z.

Worked example

Find the next letter: C, F, I, L, __.

  1. Positions are 3, 6, 9, 12.
  2. Each step adds 3.
  3. 12 + 3 = 15, which is O.
