A B C D E F G H I J K L M N O P Q R S T U V W X Y ZBH is to WF as CD is to (__)

The pattern here is based on the positions of the letters in the alphabet.

1. Look at the positions of B and H in the alphabet. B is the 2nd letter and H is the 8th letter.

2. Now look at W and F. W is the 23rd letter and F is the 6th letter.

3. If you subtract the positions of B and H from 26 (the total number of letters in the alphabet), you get the positions of W and F. Specifically, 26 - 2 = 24 and 26 - 8 = 18.

4. Apply the same logic to CD. C is the 3rd letter and D is the 4th letter.

5. Subtract these positions from 26 to find the corresponding letters. 26 - 3 = 23 and 26 - 4 = 22.

6. The 23rd letter is W and the 22nd letter is V.

So, CD is to WV.
