Let's analyze the sequence $8, 15, 22, 29, 36$ to identify a pattern and determine the next number.

Step 1: Find the differences between consecutive terms.

• Difference between $15$ and $8$: $15 - 8 = 7$
• Difference between $22$ and $15$: $22 - 15 = 7$
• Difference between $29$ and $22$: $29 - 22 = 7$
• Difference between $36$ and $29$: $36 - 29 = 7$

Step 2: Identify the pattern.

The differences between consecutive terms are constant at $7$. This suggests an arithmetic sequence where each term is obtained by adding 7 to the previous term.

Step 3: Find the next number in the sequence.

Since the pattern is to add 7 to the previous term:

$36 + 7 = 43$

Conclusion:

The next number in the sequence is 43.
