To complete the sequence CAX, FDY, IGZ, let's analyze the pattern:

1: The first letter of each term:

• C (3rd letter of the alphabet)
• F (6th letter of the alphabet)
• I (9th letter of the alphabet)
• The pattern is an increment of 3 each time. So, 9 + 3 = 12, which corresponds to L.

2:The second letter of each term:

• A (1st letter of the alphabet)
• D (4th letter of the alphabet)
• G (7th letter of the alphabet)
• The pattern is an increment of 3 each time. So, 7 + 3 = 10, which corresponds to J.

3: The third letter of each term:

• X (24th letter of the alphabet)
• Y (25th letter of the alphabet)
• Z (26th letter of the alphabet)
• The pattern is an increment of 1 each time. Following Z, the alphabet wraps around to A. So, the next letter after Z is A.

Putting these together, the next term in the sequence is: LJA

So, the complete sequence is CAX, FDY, IGZ, and LJA.
