CCAT letter series questions

Math & Logic

Track how letters shift through the alphabet and supply the next letter or group.

How to solve these

Track how letters shift through the alphabet and supply the next letter or group. The fastest route is to learn one repeatable method and then drill it under the clock. Start a free set to build the pattern recognition that makes these quick.

Worked example

Answer shown

An original, CCAT-style item with the full reasoning. This is the kind of question you will drill.

Difficulty 1

Find the next letter: E, F, G, H, I, ?

Answer: E. Here is why:

  1. Convert the letters to alphabet positions (A=1 … Z=26): E=5, F=6, G=7, H=8, I=9.
  2. The rule is: skip forward 1 letter each time.
  3. That gives position 10, which is J.

Frequently asked questions

What are CCAT letter series questions?

Track how letters shift through the alphabet and supply the next letter or group. They fall under the Math & Logic part of the CCAT, mixed in among the other types across the 50-question test.

How many letter series questions are on the CCAT?

The CCAT does not label or fix the count per type. Items are mixed, so you cannot predict how many letter series questions you will see. Training every type is the only reliable preparation.

How do I get faster at letter series questions?

Reps under the real clock. However you like to learn, speed only comes from repeated timed practice — and honest per-type numbers show you whether it is working. That feedback loop is the skill the CCAT actually rewards.
