Question

In the sequence: 13CZ, 26DY, 39EX, 52FW, ..., what should come next?

Answer 1

The next term in the sequence is 65GV, which is determined by adding 13 to the preceding number and moving backwards in the alphabet for both letters.

Step-by-step explanation:

The sequence consists of a pattern where each term has a numerical value that increases by 13 and two letters that seem to be moving backwards in the alphabet. Let's analyze the sequence step by step:

1. Start with the number 13 and add 13 each time: 13, 26, 39, 52, ... Next number will be 52 + 13 = 65.
2. The first letter starts with C and moves backwards in the alphabet: C, D, E, F, ... The next letter going backwards is G.
3. The second letter starts with Z and also moves backwards in the alphabet: Z, Y, X, W, ... The next letter going backwards is V.
4. Combine the parts for the next term in the sequence: 65GV.
