Problem Description

The worksheet shows a partially filled 10x10 grid with numbers from 1 to 100. Some cells are empty, and the task is to fill in the missing numbers.

Solution Approach

1. Understand the Pattern:
- The grid is arranged in rows and columns.
- Each row contains 10 numbers, starting from 1 and ending at 100.
- The numbers increase sequentially by 1 as you move from left to right in each row.
- After reaching the end of a row (i.e., every 10th number), the next number starts on the next row.

2. Identify Missing Numbers:
- Look for gaps in the sequence where numbers are missing.
- For example:
- In the first row, the numbers are complete.
- In the second row, the number after 13 is missing.
- Continue this process for all rows.

3. Fill in the Missing Numbers:
- Use the sequential pattern to determine the missing numbers.
- For instance:
- After 13 in the second row, the next number should be 14.
- After 35 in the fourth row, the next number should be 36.
- Continue this process until all gaps are filled.

4. Verify the Sequence:
- Ensure that each row and column follows the correct numerical order.
- Double-check that no numbers are skipped or repeated.

Explanation of Key Steps

1. Sequential Counting: Each number increases by 1 as you move from left to right.
2. Row Continuity: After reaching the 10th number in a row, the next number starts on the next row.
3. Pattern Recognition: Use the existing numbers to identify the missing ones and ensure consistency.
