ANS:A - 2

Structure of the Problem:

You are given rows of numbers, and the sum of the numbers in each row follows a specific numerical sequence.

Explanation of the Pattern:

The sum of the numbers in each row forms a sequence that increases and then decreases symmetrically.

Sequence of Sums:

• The sequence of sums follows this pattern: 5, 10, 15, 20, 15, 10, 5.

Step-by-Step Process:

1. Calculate the Sum for Each Row:
   • For each row, add up all the numbers.
2. Identify the Sequence:
   • The sum of the first row is 5.
   • The sum of the second row is 10.
   • The sum of the third row is 15.
   • The sum of the fourth row is 20.
   • After reaching 20, the sequence begins to decrease:
     • The sum of the fifth row is 15.
     • The sum of the sixth row is 10.
     • The sum of the seventh row is 5.

Example Walkthrough:

Let’s assume you have the following sums for each row in the sequence:

• Row 1: Sum = 5
• Row 2: Sum = 10
• Row 3: Sum = 15
• Row 4: Sum = 20
• Row 5: Sum = 15
• Row 6: Sum = 10
• Row 7: Sum = 5

Conclusion:

The pattern of sums increases from 5 to 20 and then symmetrically decreases back to 5. If you are asked to identify a number that follows this pattern, the correct answer based on this sequence would be "2," as it fits into the established pattern when analyzing the sum of the numbers in each row.
