The image contains a table with two rows of numbers, and there is a question asking to find \( A + B \). Here’s the content extracted from the table:

\[
\begin{array}{|c|c|c|c|c|c|}
\hline
X & 2 & 4 & 7 & 11 & A & 22 \\
\hline
Y & 20 & 18 & 15 & 11 & 8 & B \\
\hline
\end{array}
\]

The goal is to find \( A + B \).

By analyzing the pattern between the top row and the bottom row, we see a pattern where:

- \( X = Y \)
- The difference between the top and bottom values of each column seems to follow a decreasing pattern in both rows.

I'll analyze the pattern to calculate \( A \) and \( B \).It looks like the variable \( A \) is missing in the calculation, which causes a problem. Let's analyze the differences between the known values first and then find \( A \) and \( B \) based on the pattern.

Here’s the difference between each pair of values in the columns:

\[
\text{Difference} = \text{Bottom row value} - \text{Top row value}
\]

We can compute:

- \( 20 - 2 = 18 \)
- \( 18 - 4 = 14 \)
- \( 15 - 7 = 8 \)
- \( 11 - 11 = 0 \)

There seems to be a decreasing difference (18, 14, 8, 0). Let's predict the next difference for \( A \) and \( B \) based on this pattern.

The difference should be decreasing by 6, meaning the difference for \( A \) and \( B \) should be \( -6 \). Now I’ll solve for \( A \) and \( B \).Based on the pattern, the values of \( A \) and \( B \) are:

- \( A = 2 \)
- \( B = 8 \)

Thus, \( A + B = 2 + 8 = 10 \).

Here are five related questions to further explore the topic:
1. How do arithmetic sequences help in finding patterns like this?
2. What is the difference between linear and non-linear patterns in number series?
3. How can we predict missing values in a table using difference patterns?
4. What other types of number patterns can be found in such matrices?
5. How would the problem change if the differences were increasing instead of decreasing?

**Tip:** When analyzing number patterns, always check if the differences are constant or follow a particular rule like increasing or decreasing by a fixed number.

This problem involves solving for A and B in a number pattern table by recognizing an arithmetic sequence. Follow a step-by-step explanation to determine the difference between rows and calculate the missing values. Suitable for Grades 5-7.
