What is the next number in the sequence: 5, 11, 17, 23, ...?

To determine the next number in the sequence 5, 11, 17, 23, we first need to identify the pattern in the differences between the numbers.

Starting from the first number and moving to the next, we can calculate the differences:

• From 5 to 11, the difference is 11 - 5 = 6.

• From 11 to 17, the difference is 17 - 11 = 6.

• From 17 to 23, the difference is 23 - 17 = 6.

This shows that each number in the sequence is increasing by 6. To find the next number, we simply add 6 to 23:

23 + 6 = 29.

Thus, the next number in the sequence is 29, confirming that this is the correct answer. The consistent addition of 6 demonstrates a linear relationship in the sequence, making it straightforward to predict the next term.
