Canadian Forces Aptitude Test (CFAT) Practice

Question: 1 / 400

What is the next number in the sequence: 1, 7, 13, 19?

25

To determine the next number in the sequence 1, 7, 13, 19, it helps to identify the pattern in the series. Examining the differences between consecutive numbers:

- The difference between 1 and 7 is 6.

- The difference between 7 and 13 is also 6.

- The difference between 13 and 19 remains 6.

This shows that each number is obtained by adding 6 to the previous number. Continuing this pattern, if you add 6 to the last number in the sequence, which is 19, you arrive at:

19 + 6 = 25.

Therefore, the next number in the sequence is 25, confirming that this is the correct answer. The other choices do not follow this consistent additive pattern, thus making them unsuitable as the next number in the sequence.
