How Thena would solve it

  1. Look at the first letters on their own: A, B, C, D. Each moves one place on.

  2. Now the second letters: Z, Y, X, W. Each moves one place back.

  3. Put the next of each together: E and V.

    A B C D E

    Z Y X W V

    The answer is EV

Answer: EV

The usual mistakes

  • Looking only at the first letter

    Work out each letter of the pair on its own.

  • Counting the start letter

    Count the hops between letters, not the letters.

  • Going the wrong way

    Check whether each letter moves towards Z or back towards A.
